+What's an Enterprise Router?
+An enterprise router connects virtual private clouds (VPCs) and on-premises networks to build a central hub network. It has high specifications, provides high bandwidth, and delivers high performance. Enterprise routers use the Border Gateway Protocol (BGP) to learn, dynamically select, or switch between routes, thereby ensuring the service continuity and significantly improving network scalability and O&M efficiency.
+
+
Figure 1 and
Figure 2 show the networks with and without enterprise routers, respectively.
Table 1 compares the two networks.

+ |
+Benefits of Using Enterprise Routers
+ |
+
|---|
+
+Communications among VPCs in the same region
+ |
+- Create six VPC peering connections between these four VPCs in the same region.
- Add 12 routes, with three routes for each VPC to communicate with the other three VPCs.
+ |
+- Attach the four VPCs to one enterprise router. This router can then handle the traffic from and to all the connected VPCs.
- Add routes to the route tables of these four VPCs for routing traffic through the enterprise router. The enterprise router can automatically learn the VPC CIDR blocks and add them to its route table.
+ |
+- There is no need to configure a large number of VPC peering connections.
- Fewer routes need to be added, simplifying the maintenance.
+ |
+
+Communications between an on-premises data center and VPCs
+ |
+Establish Direct Connect connections between each VPC and the data center.
+ |
+Attach the Direct Connect connection to the enterprise router. These VPCs can then share the connection.
+ |
+- Route propagation simplifies the route configuration and the O&M.
- Multiple lines work in load-sharing or active/standby mode to achieve higher availability.
+ |
+
+
+
+
+
+
The comparison shows that the network with enterprise routers is simpler and highly scalable and is also easier to maintain.
+
Why Using Enterprise Routers
+Enterprise routers have the following advantages:
+
High Performance
Enterprise routers use exclusive resources and are deployed in clusters to deliver the highest possible performance for workloads on large-scale networks.
+
+
High Availability
Enterprise routers can be deployed in multiple availability zones to work in active-active or multi-active mode, thereby ensuring service continuity and real-time seamless switchovers.
+
+
Simplified Management
Enterprise routers can connect to multiple VPCs, Direct Connect connections, or enterprise routers in different regions and route traffic among them. The network topology is simpler and the network is easier to manage and maintain.
- For cross-VPC communications, you only need to maintain the route tables on the VPCs without requiring so many VPC peering connections.
- For communications between VPCs and an on-premises data center, the VPCs can connect to an enterprise router and then communicate with the data center over one Direct Connect connection. You do not need to establish a Direct Connect connection between the data center and each of the VPCs.
- Enterprise routers can automatically learn, update, and synchronize routes, eliminating the need to manually configure or update routes whenever the network topology changes.
+
+
+
Seamless Failover Between Lines
Enterprise routers use the Border Gateway Protocol (BGP) to select the best path from multiple lines working in load-sharing or active/standby mode. If a single line fails, services can be failed over to another functioning line within seconds to ensure service continuity.
+
+
When to Use Enterprise Routers
+You can use enterprise routers to build cloud, on-premises, or hybrid networks. Here are some typical application scenarios:
+
+
Scenario 1: Multiple VPCs communicating or not communicating with each other on the cloud, but communicating with the on-premises data center through a Direct Connect connection
Figure 1 Diagram for scenario 1
+
+
Table 1 Using enterprise routers in scenario 1Customer Requirements
+ |
+Multiple service networks communicate or do not communicate with each other on the cloud but communicate with the on-premises data center. For example, an enterprise requires three VPCs for running their workloads on the public cloud, and the three VPCs (services A, B, and C) need to access public services in VPC 4 and the on-premises data center.
+ |
+
|---|
+Pain Points
+ |
+- VPC peering connections are required for communications among these VPCs, but they will complicate the network topology and make the network hard to manage.
- VPC peering connections and routes are required for the public service VPC to communicate with each VPC. However, VPC peering connections do not fit in large-scale networks because of the following limitations:
- A maximum of 50 VPC peering connections can be created in one region.
- A VPC route table can have a maximum of 200 routes.
+ - Direct Connect connections are required for each VPC to communicate with the on-premises data center, but they will incur high costs.
+ |
+
|---|
+Benefits of Using Enterprise Routers
+ |
+- VPCs can be associated with different route tables on the enterprise router to enable communication or isolation. The network topology is simple and easy to manage.
- Enterprise routers can route traffic among all the connected VPCs without the need to configure a large number of VPC peering connections.
- Each enterprise router can have a maximum of 2,000 routes in each route table, making it ideal for large-scale complex networks.
+ - Multiple VPCs can access the on-premises data center over a Direct Connect connection, eliminating the need to configure multiple Direct Connect connections and reducing the costs.
+ |
+
|---|
+
+
+
+
+
Scenario 2: Dynamic switchover between multiple Direct Connect connections
Figure 2 Diagram for scenario 2
+
+
+
Table 2 Using enterprise routers in scenario 2Customer Requirements
+ |
+Some services run on the public cloud and some in the on-premises data center. Two independent high-bandwidth Direct Connect connections are deployed between the public cloud and the data center to enable communication between them.
+ |
+
|---|
+Pain Points
+ |
+Two Direct Connect connections are independent of each other and cannot work in load-sharing or active/standby mode.
+ |
+
|---|
+Benefits of Using Enterprise Routers
+ |
+Direct Connect connections are connected to the enterprise router. - Two Direct Connect connections can work in load-sharing mode to ensure high bandwidth and reliability.
- Two Direct Connect connections can also work in active/standby mode. If one of the connections becomes unavailable, services are switched over to the other available connection within seconds, preventing service interruptions.

+An enterprise router is a high-performance centralized router that supports route learning. When creating an enterprise router, you can set parameters such as its region, AZ, and name.
+After an enterprise router is created, you can still change its parameters based on service requirements.
+ |
+Creating an Enterprise Router
+ |
+
+Attachments
+ |
+You can add attachments to attach network instances to the enterprise router.
+Different network instances are attached through different consoles. - VPCs are attached through the Enterprise Router console.
- Virtual gateways are attached through the Direct Connect console.
+ |
+Attachment Overview
+ |
+
+Route tables
+ |
+Route tables are used by enterprise routers to forward packets. Route tables contain associations, propagations, and routes.
+An enterprise router can have multiple route tables. You can associate attachments with different route tables to enable communication or isolation between network instances.
+ |
+Route Table Overview
+ |
+
+Associations
+ |
+Associations are created manually or automatically to associate attachments with enterprise router route tables. - Manually: Select a route table and create an association for an attachment in the route table.
- Automatically: You just need to enable Default Route Table Association and specify the default route table. The system automatically creates an association for an attachment in the default route table.
+ |
+Association Overview
+ |
+
+Propagations
+ |
+A propagation is created manually or automatically to enable an enterprise router to learn the routes to an associated attachment. - Manually: Select a route table and create a propagation for an attachment in the route table.
- Automatically: You just need to enable Default Route Table Propagation and specify the default route table. A propagation is automatically created for an attachment in the default propagation route table.
+ |
+Propagation Overview
+ |
+
+Routes
+ |
+A route consists of information such as the destination address, next hop, and route type. There are two types of routes: - Propagated routes
- Static routes
+ |
+Route Overview
+ |
+
+Sharing
+ |
+You are the owner of the enterprise router, and other accounts are the users of your enterprise router.
+After you share your enterprise router with other accounts, these other users can attach their network instances to your enterprise router, so that their network instances can access your enterprise router.
+This allows VPCs in the same region but different accounts to be attached to the same enterprise router.
+ |
+Sharing Overview
+ |
+
+Flow logs
+ |
+The flow log function records traffic logs of attachments on enterprise routers in real time. The logs allow you to monitor the network traffic of attachments and analyze network attacks, helping you achieve efficient O&M.
+Flow logs can capture traffic of the following types of attachments:

+ |
+
+Monitoring
+ |
+You can use Cloud Eye to monitor the network status of enterprise routers and their attachments.
+ |
+Supported Metrics
+ |
+
+Auditing
+ |
+You can use Cloud Trace Service (CTS) to record operations associated with your enterprise routers for future query, audit, and backtracking.
+ |
+Key Operations Recorded by CTS
+ |
+
+Tags
+ |
+Tags are used to identify cloud resources. You can add tags to enterprise routers and route tables.
+ |
+Overview
+ |
+
+Quotas
+ |
+Quotas can limit the number or amount of resources available to users, for example, how many enterprise routers can be created, how many attachments can be created for each enterprise router, and how many routes can be added to each route table.

Permissions
+If you need to assign different permissions to employees in your enterprise to control their access to your cloud resources, you can use the Identity and Access Management (IAM) for fine-grained permissions management. IAM provides functions such as identity authentication, permissions management, and access control.
+
On the IAM console, you can create IAM users and assign permissions to control their access to specific resources. For example, you can create IAM users for software developers and assign permissions to allow them to use enterprise router resources but disallow them from performing any high-risk operations such as deleting such resources.
+
IAM is free of charge.
+
For more information, see IAM Service Overview.
+
Enterprise Router Permissions
By default, new IAM users do not have any permissions assigned. You need to add them to one or more groups and attach policies or roles to these groups so that these users can inherit permissions from the groups and perform specified operations on cloud services.
+
An enterprise router is a project-level service deployed in a specific region. You need to select a project for which the permissions will be granted. If you select All projects, the permissions will be granted for all the projects. You need to switch to the authorized region before accessing an enterprise router.

How Enterprise Routers Work
+You can attach your network connections to an enterprise router to quickly construct diversified networks and meet various service requirements. Figure 1 shows the process of using an enterprise router, including creating an enterprise router, adding attachments to the enterprise router, and configure routes.
+
Currently, enterprise routers support the following attachments:
- VPC attachment: Attach VPCs from the same region as that of an enterprise router to the router.
- Virtual gateway attachment: Attach Direct Connect virtual gateways from the same region as that of an enterprise router to the router.
+
+
Figure 1 Processing of using an enterprise router
+
The following describes how an enterprise router works.

+Response from Direct Connect virtual gateway to VPC 1
+ |
+After receiving responses from the virtual gateway to VPC 1, enterprise router 1 searches the default route table for the route to VPC 1 and forwards the responses through this route.
+ |
+
+2
+ |
+Request from VPC 2 to Direct Connect virtual gateway
+ |
+Enterprise router 1 cannot forward requests from VPC 2 to the virtual gateway because the custom route table of enterprise router 1 that is associated with VPC 2 does not contain the route to this virtual gateway.

Route Tables
Route tables are used by enterprise routers to forward packets. Route tables contain associations, propagations, and routes. Route tables are classified into custom and default route tables, as detailed in Table 4.
+
+
Table 4 Route tablesRoute Table
+ |
+Description
+ |
+
|---|
+
+Custom route table
+ |
+You can create multiple custom route tables on an enterprise router and use different routes for flexible communication and isolation between network instances.
+ |
+
+Default route table
+ |
+If you enable Default Route Table Association and Default Route Table Propagation, the system then automatically associates and propagates new attachments with the default route table.
+You can specify a custom route table as the default route table. If you do not specify any route table as the default route table, the system automatically creates a default route table.
+ |
+
+
+
+
+
+
Associations
Each attachment can be associated with one route table for:
- Packet forwarding: Packets from the attachment are forwarded through the routes specified in the associated route table.
- Route propagation: The routes in the associated route tables are automatically propagated to the route table of the attachment.
+
+
Not all attachments can propagate routes. For details, see
Table 5.

+
+
+
+
+
+
+
Route Propagation
You can create a propagation for each attachment to propagate routes to one or more route tables on an enterprise router.
+
For VPC attachments, their CIDR blocks are propagated to the enterprise router. For other attachments, all routes are propagated to the enterprise router. For details, see

+Route Table Overview
+Route tables are used by enterprise routers to forward packets. Each route table contains associations, propagations, and routes. Route tables are classified into custom route tables and default route tables.
+
+
Table 1 Route tablesRoute Table
+ |
+Description
+ |
+
|---|
+
+Custom route table
+ |
+- A custom route table is an additional route table you optionally create for an enterprise router.
- An enterprise router can have multiple custom route tables. You can associate attachments with different route tables to enable communication or isolation between network instances.
+ |
+
+Default route table
+ |
+A default route table is automatically created when an enterprise router is created. There are two types of default route tables: default association route table and default propagation route table. You can specify a route table both as the default association route table and the default propagation route table. You can also specify one route table as the default association route and another route table as the default propagation route table.
+- If Default Route Table Association is enabled and the default association route table is specified, attachments will be associated with the default association route table.
If no default association route table is specified, a route table named defaultRouteTable will be created and used as the default association route table.
+ - If Default Route Table Propagation is enabled and the default propagation route table is specified, attachments will be propagated to the default propagation route table.
If no default propagation route table is specified, a route table named defaultRouteTable will be created and used as the default propagation route table.
+ - If both Default Route Table Association and Default Route Table Propagation are enabled but the default association route table and the default propagation route table are not specified, the route table named defaultRouteTable will be used as both the default association route table and the default propagation route table.
- If there is already a route table named defaultRouteTable, no additional defaultRouteTable will be created.
- You can replace the default route table with a custom route table if needed.

+Route Overview
+What Is a Route?
Routes are used to forward packets. A route contains information such as the destination, next hop, and route type.
+
You can create a propagation for attachments to automatically propagate routes to route tables or manually add static routes to route tables.
+
Figure 1 Propagated routes and static routes
+
+
Table 1 Route typesRoute Type
+ |
+Description
+ |
+How to Create
+ |
+Description
+ |
+
|---|
+
+Propagated routes
+ |
+Propagated routes are routes that attachments propagate to the route tables of the enterprise router. They cannot be modified or deleted.
+ |
+To create a propagation, see Creating a Propagation for an Attachment in the Route Table.
+ |
+Routes are classified into propagated routes and static routes. The routes shown in Figure 1 are described as follows: - Propagated routes are from:
- Propagations automatically created in the default route table of the enterprise router for attachments, such as VPC 1, VPC 2, and virtual gateway 1 attachments.
- Propagations manually created in the custom route table of the enterprise router for attachments, such as VPC 1, virtual gateway 1, and virtual gateway 2 attachments.
+ - Static routes are manually added to the custom route table of the enterprise router for attachments, such as VPC 3 and VPC 4 attachments.
+ |
+
+Static routes
+ |
+Static routes are manually created and can be modified or deleted.
+ |
+To create a route, see Creating a Static Route.
+ |
+
+
+
+
+
+
Route Priority
If there are multiple routes with the same destination but different targets in a route table, the route priority is as follows:
+
Static route > propagated route for VPC attachment > propagated route for virtual gateway attachment route
+
- Static routes are manually configured and the destination of each static route must be unique in a route table.
- Propagated routes are automatically learned by the system and may have the same destination in a route table.
- A static route and a propagated route may have the same destination in a route table.
+
+
+
Creating a Static Route
+Scenarios
You can create static routes in a route table of an enterprise router.
+
Static routes are classified into common routes and blackhole routes. A blackhole route only has a destination and has no next hop. It drops all traffic sent to the specified destination.
+
+
Procedure
- Log in to the management console.
- Click in the upper left corner and select the desired region and project.
- Click Service List and choose Networking > Enterprise Router.

+Creating a User and Granting Permissions
+This section describes how to use IAM to implement fine-grained permissions control for your Enterprise Router resources. With IAM, you can:
+
- Create IAM users for employees based on the organizational structure of your enterprise. Each IAM user has their own security credentials, providing access to Enterprise Router resources.
- Assign only the minimum permissions required for users to perform a given task.
- Entrust an account or a cloud service to perform professional and efficient O&M on your Enterprise Router resources.
+
If your account does not require individual IAM users, skip over this section.
+
Figure 1 shows the procedure for granting permissions.
+
Prerequisites
You have learned about the permissions supported by Enterprise Router and choose policies or roles according to your requirements. For details, see Permissions.
+
For the permissions of other services, see Permission Description.
+
+
Process Flow
Figure 1 Process for granting Enterprise Router permissions
+
+
- Create a user group and assign permissions to it.
Create a user group on the IAM console, and assign the ER ReadOnlyAccess permission to the group.
+ - Create an IAM user and add it to the user group.
Create a user on the IAM console and add the user to the group created in 1.
+ - Log in and verify permissions.
Log in to the management console as the created user, switch to the authorized region, and verify that the user has only the ER ReadOnlyAccess permission.
+- Click Service List and choose Enterprise Router. Then click Create Enterprise Router in the upper right corner. If the enterprise router fails to be created, the ER ReadOnlyAccess permission has taken effect.
- Choose any other service in the Service List. If a message appears indicating insufficient permissions to access the service, the ER ReadOnlyAccess permission has already taken effect.
+
+
+
Enterprise Router Custom Policies
+Custom policies can be created to supplement the system-defined policies of Enterprise Router.
+
You can create custom policies in either of the following ways:
+
- Visual editor: Select cloud services, actions, resources, and request conditions. This does not require knowledge of policy syntax.
- JSON: Edit JSON policies from scratch or based on an existing policy.
+
For details about how to create custom policies, see Creating a Custom Policy. The following section contains examples of common Enterprise Router custom policies.
+
Example Custom Policies
- Example 1: Allowing users to create and delete enterprise routers
{
+ "Version": "1.1",
+ "Statement": [
+ {
+ "Effect": "Allow",
+ "Action": [
+ "er:instances:create",
+ "er:instances:delete"
+ ]
+ }
+ ]
+}
+ - Example 2: Denying enterprise router deletion
A policy with only Deny permissions must be used in conjunction with other policies to take effect. If the policies assigned to a user contain both Allow and Deny actions, the Deny actions take precedence over the Allow actions.
+The following method can be used if you need to assign the ER FullAccess permission to a user but also forbid the user from deleting enterprise routers. Create a custom policy for denying enterprise router deletion, and assign both policies to the group the user belongs to. Then the user can perform all operations on Enterprise Router except deleting enterprise routers. The following is an example of a deny policy:
+{
+ "Version": "1.1",
+ "Statement": [
+ {
+ "Effect": "Deny",
+ "Action": [
+ "er:instances:delete"
+ ]

+Overview
+What Is a Tag?
Tags are used to identify the cloud resources for purposes of easy categorization and quick search. You can add tags to enterprise routers, attachments, and route tables using either of the methods:
- Add tags when you create an enterprise router, attachment, or route table.
- Add tags on the details page of an existing enterprise router, attachment, or route table. You can also edit or delete tags.
+
+
+
Basic Knowledge About Tags
Tags are used to identify cloud resources. When you have many cloud resources of the same type, you can use tags to classify cloud resources by dimension (for example, use, owner, or environment).
+
Figure 1 shows how tags work. In this example, you assign two tags to each cloud resource. Each tag contains a key and a value that you define. The key of one tag is Owner, and the key of another tag is Usage. Each tag has a value.
+
You can quickly search for specific cloud resources based on the tags added to them. For example, you can define a set of tags for cloud resources in an account to track the owner and usage of each cloud resource, making resource management easier.
+
Figure 1 Example tags added for Enterprise Router
+
+
Constraints on Using Tags
- Each tag consists of a tag key and a tag value. The rules for naming a tag key and a tag value are as follows:
Tag key
- Cannot be left blank.
- Can contain a maximum of 36 characters.
- Can contain only digits, letters, hyphens (-), underscores (_), and at signs (@).
+
Tag value

+Quick Start
+Background
Four VPCs are created in region A on public cloud and they need to communicate with each other.
+
You can create an enterprise router in region A and attach the four VPCs to the enterprise router. The enterprise router can route traffic among the VPCs so that they can communicate with each other.
+
Figure 1 Communications among VPCs in the same region
+
This document describes how to use an enterprise router to quickly allow multiple VPCs in the same region to communicate with each other.
+
You can share an enterprise router with different accounts to attach VPCs of these accounts to the same enterprise router for communication.
+
+
+
Procedure
Figure 2 shows the procedure for using an enterprise router to allow multiple VPCs in the same region to communicate with each other.
+
Figure 2 Flowchart for connecting VPCs in the same region
+
+
Table 1 Steps for connecting VPCs in the same regionNo.
+ |
+Step
+ |
+Description
+ |
+
|---|
+
+1
+ |
+Step 1: Plan Networks and Resources
+ |
+Plan CIDR blocks and the number of resources.
+ |
+
+2
+ |
+Step 2: Create an Enterprise Router
+ |
+Create one enterprise router for connecting VPCs in the same region.
+ |
+
+3
+ |
+Step 3: (Optional) Create VPCs and ECSs
+ |
+Create four VPCs and four ECSs. You can change the resource quantity and specifications as needed.
+If you already have these resources, skip this step.
+ |
+
+4
+ |
+Step 4: Create VPC Attachments to the Enterprise Router
+ |
+Attach the four VPCs to the enterprise router.
+ |
+
+5
+ |
+Step 5: (Optional) Add Routes to VPC Route Tables
+ |
+Add routes to the route tables of the VPCs for communication with the enterprise router.
+- If you enable Auto Add Routes when creating a VPC attachment, you do not need to manually add static routes to the VPC route table. Instead, the system automatically adds routes (with this enterprise router as the next hop and 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 as the destinations) to all route tables of the VPC.
- If an existing route in the VPC route tables has a destination to 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16, the routes will fail to be added. In this case, do not need to enable Auto Add Routes. After the attachment is created, manually add routes.
+ |
+
+6
+ |
+Step 6: Verify Connectivity Among VPCs
+ |
+Log in to the ECS and run the ping command to verify the connectivity among VPCs.
+ |
+
+
+
+
+
+
Step 1: Plan Networks and Resources
+To use an enterprise router to connect VPCs in the same region, you need to:
- Network Planning: Plan CIDR blocks of VPCs and subnets, and route tables of VPCs and the enterprise router.
- Resource Planning: Plan the quantity, names, and parameters of cloud resources, including VPCs, ECSs, and the enterprise router.
+
+
Network Planning
Figure 1 and Table 2 show the network planning and its description for communications among VPCs in the same region.
+

+
+
Table 1 Network traffic flowsScenario

+
|---|
+
+Request from VPC 1 to VPC 3
+ |
+- The route table of VPC 1 has a route with next hop set to the enterprise router to forward traffic from VPC 1 to the enterprise router.
- The route table of the enterprise router has a propagated route with next hop set to the VPC 3 attachment to forward traffic from the enterprise router to VPC 3.
+ |
+
+Response from VPC 3 to VPC 1
+ |
+- The route table of VPC 3 has a route with next hop set to the enterprise router to forward traffic from VPC 3 to the enterprise router.
- The route table of the enterprise router has a propagated route with next hop set to the VPC 1 attachment to forward traffic from the enterprise router to VPC 1.

+VPC
+ |
+- The CIDR blocks of the VPCs to be connected cannot overlap with each other.
In this example, the CIDR blocks of the VPCs are propagated to the enterprise router route table as the destination in routes. The CIDR blocks cannot be modified and overlapping CIDR blocks may cause route conflicts.
+If your existing VPCs have overlapping CIDR blocks, do not use propagated routes. Instead, you need to manually add static routes to the route table of the enterprise router. The destination can be VPC subnet CIDR blocks or smaller ones.
+ - Each VPC has a default route table.
- Routes in the default route table can be:
- Local: a system route for communications between subnets in a VPC.
- Enterprise router: custom routes with 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 as the destinations for routing traffic from a VPC subnet to the enterprise router. See Table 3 for route details.
+
+ |
+
+Enterprise router
+ |
+After Default Route Table Association and Default Route Table Propagation are enabled and a VPC attachment is created, the system will automatically: - Associate VPC attachments with the default route table of the enterprise router.
- Propagate VPC attachments with the default route table of the enterprise router. The route table automatically learns the VPC CIDR block as the destination of routes. For details, see Table 4.
+ |
+
+ECS
+ |
+The four ECSs are in different VPCs. If the ECSs are associated with different security groups, add rules to their security groups to allow access to each other.

- If an existing route in the VPC route tables has a destination to 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16, the routes will fail to be added. In this case, do not to enable Auto Add Routes. After the attachment is created, manually add routes.
- Do not set the destination of a route (with an enterprise router as the next hop) to 0.0.0.0/0 in the VPC route table. If an ECS in the VPC has an EIP bound, the VPC route table will have a policy-based route with 0.0.0.0/0 as the destination, which has a higher priority than the route with the enterprise router as the next hop. In this case, traffic is forwarded to the EIP and cannot reach the enterprise router.

+
+
+
+
Adding VPC Attachments to an Enterprise Router
+Scenarios
This section describes how to attach VPCs to an enterprise router so that these VPCs can communicate with each other.
+
+
Notes and Constraints
- If you use the propagated routes of a VPC attachment, the route table of the enterprise router automatically learns the VPC CIDR block as the destination of routes. The CIDR block cannot be changed. To ensure that routes in the route table do not conflict, the CIDR blocks of all VPCs attached to the enterprise router cannot overlap. Otherwise, communication fails.
- If your existing VPCs have overlapping CIDR blocks, do not use propagated routes. Instead, manually add static routes to the route table of the enterprise router. The destination of the routes can be VPC subnet CIDR blocks or smaller ones.
+
+
Procedure
- Log in to the management console.
- Click in the upper left corner and select the desired region and project.
- Click Service List and choose Networking > Enterprise Router.
The Enterprise Router homepage is displayed.

- Create a custom route table for the enterprise router. For details, see Creating a Route Table.
- Create associations for the attachments of the enterprise router. For details, see Creating an Association for an Attachment in a Route Table.
- Use either of the following methods to add routes for the attachment to the route table:
+
+
+
+
Region and AZ
+Concept
A region and availability zone (AZ) identify the location of a data center. You can create resources in a specific region and AZ.
+
- A region is a physical data center, which is completely isolated to improve fault tolerance and stability. The region that is selected during resource creation cannot be changed after the resource is created.
- An AZ is a physical location where resources use independent power supplies and networks. A region contains one or more AZs that are physically isolated but interconnected through internal networks. Because AZs are isolated from each other, any fault that occurs in one AZ will not affect others.
+
Figure 1 shows the relationship between regions and AZs.
+
Figure 1 Regions and AZs
+
+
Selecting a Region
Select a region closest to your target users for lower network latency and quick access.
+
+
Selecting an AZ
When deploying resources, consider your applications' requirements on disaster recovery (DR) and network latency.
+
- For high DR capability, deploy resources in different AZs within the same region.
- For lower network latency, deploy resources in the same AZ.
+
+
Regions and Endpoints
Before you use an API to call resources, specify its region and endpoint. For more details, see Regions and Endpoints.

+Sharing Overview
+What Is Sharing?
You can share an enterprise router in your account with other accounts.
- You are the owner of the enterprise router.
- Other accounts are the users of the enterprise router.
+
+
After you share your enterprise router with other accounts, these other users can attach their network instances to your enterprise router, so that their network instances can access your enterprise router.
+
You can share an enterprise router in your account with other accounts so that these other accounts can attach their VPCs to your enterprise router.
+
This example uses account A, account B, and account C to describe how you can build a network using one enterprise router. Table 1 describes the resources of each account.
+
If account A shares enterprise router (ER-A) with account B and account C, the VPCs of accounts B and C can be attached to ER-A. Figure 1 shows the networking.
+

Allowed Operations by the Owner and Other Users
The owner can perform all operations but these other users can perform only some of the operations.
Table 2 lists the operations that other users can perform.
+
+
Other users cannot view the Route tables, Sharing, Flow logs, and Tags tabs of the enterprise router.
+
+
+
+
Sharing an Enterprise Router with Other Users
As the owner, you can share your enterprise router with other users. These other users can create attachments for your enterprise router.
- If Auto Accept Shared Attachments is not enabled on your enterprise router, you must accept the attachment creation requests from other users.

+Flow Log Overview
+What Is a Flow Log?
Log Tank Service (LTS) can record flow logs for enterprise routers. A flow log records traffic of attachments on enterprise routers in real time. These logs allow you to monitor the network traffic of attachments and analyze network attacks, improving your O&M efficiency.
+
Flow logs can capture traffic of the following types of attachments:
+
+
+
Creation Process
Before creating a flow log for an enterprise router, you need to create a log group and a log stream on the LTS console.
+
Figure 1 Process of creating a flow log
+
+
Notes and Constraints
- By default, you can create a maximum of 20 flow logs.
- For TCP and UDP fragments, flow logs can record only the first fragment. Other fragments cannot be recorded because of incomplete packet header.
- Flow logs can only record traffic generated for network communications and do not capture traffic generated by the network. For example, BGP traffic used by an enterprise router to learn routes of attachments is not recorded.
+
+
Creating a Flow Log
+Scenarios
This section describes how to create a flow log to record information about the traffic of enterprise router attachments.
+
+
Notes and Constraints
Only one flow log can be created for an attachment in the same log group and log stream.
+
+
Procedure
- Log in to the management console.
- Click in the upper left corner and select the desired region and project.

+Why Traffic Can't Be Forwarded from a VPC with a Route Destination of 0.0.0.0/0 to Its Enterprise Router?
+Scenarios
Traffic cannot be forwarded from a VPC to the enterprise router that it is attached to if you set the destination of a route in the VPC route table to 0.0.0.0/0 and:
+
+
+
Solutions
Select a solution based on your actual service scenario.
- Solution 1: Change the destination (0.0.0.0/0) of the default route to a specific IP address range, for example, 192.168.0.0/16.
- Solution 2: Add eight routes with specific IP address ranges as the destination to replace the default route (with a destination of 0.0.0.0/0).

How Do I Route Traffic to 100.64.x.x Through an Enterprise Router?
+Scenarios
A route with 100.64.x.x as the destination and an enterprise router as the next hop cannot be added to a VPC route table.
+
+
Solutions
If you want to route traffic to 100.64.x.x through an enterprise router, you need to create a transit VPC. Figure 1 shows the network diagram.
+
Figure 1 Transit VPC network diagram
+
The request traffic from the service VPC to the on-premises data center will be forwarded through the transit VPC, but the response traffic will not. For details, see
Table 1.
+
Table 1 Network traffic flowsPath
+ |
+Description

|---|
+
+Request traffic: service VPC → transit VPC → enterprise router → virtual gateway → on-premises data center
+ |
+- The service VPC route table has a route with the VPC peering connection as the next hop to forward traffic from the service VPC to the transit VPC.
- The transit VPC route table has a route with next hop set to the enterprise router to forward traffic from the transit VPC to the enterprise router.
- The enterprise router route table has a route with next hop set to virtual gateway attachment to forward traffic from the enterprise router to the virtual gateway.
- The virtual gateway is connected to the virtual interface. Traffic from the virtual gateway is forwarded to the physical connection through the remote gateway of the virtual interface
- Traffic is sent to the on-premises data center over the connection.
+ |
+
+Response traffic: on-premises data center → virtual gateway → enterprise router → service VPC
+ |
+- Traffic is forwarded to the virtual interface through the connection.
- The virtual interface is connected to the virtual gateway. Traffic from the virtual interface is forwarded to the virtual gateway through the local gateway of the virtual interface.
- Traffic is forwarded from the virtual gateway to enterprise router.
- The enterprise router route table has a route with next hop set to the service VPC attachment to forward traffic from the enterprise router to the service VPC.
+ |
+
+
+
+
+
+
The required resources and routes are as follows:

- Create a transit VPC, attach it to the enterprise router, and associate the transit VPC with the default route table of the enterprise router.
- The subnet of the transit VPC cannot overlap with that of the service VPC. Otherwise, the VPC peering connection to be created in 2 cannot take effect.
- The transit VPC cannot have the following situations. Otherwise, the default route (0.0.0.0/0) to be configured in 3 cannot forward traffic.
- An ECS in the VPC has an EIP bound.
- The VPC is being used by ELB, NAT Gateway, VPC Endpoint, or DCS.
+
+ - Create a VPC peering connection between the service VPC and transit VPC.
You do not need to add routes for the VPC peering connection. For details about the routes to be added, see 3.
+
+ - Add routes to the VPC route tables.
For details about required routes, see
Table 3.
- Add the route to the service VPC route table.
- Add two routes to the transit VPC route table.

How Do I Enable Two Attachments of an Enterprise Router to Learn Routes from Each Other?
+If you want two attachments of an enterprise router to learn routes from each other, the router and each attachment must have a unique ASN. In this way, the enterprise router advertises the learned route information between the attachments.
+
If you want two virtual gateways attached to the same enterprise router to learn routes from each other, their ASNs can be as follows:
- Enterprise router: 64512
- Virtual gateway attachment A: 64513 (BGP ASN of virtual gateway A)
- Virtual gateway attachment B: 64515 (BGP ASN of virtual gateway B)
+
+
VPC attachments do not support route learning.
