Central Networks

Scenarios

After an enterprise router is created, you can create a central network and add the enterprise router to a policy of the central network. In this way, resources can communicate with each other across regions, and network resources in each region can be managed centrally.

Constraints

• Before building a central network, you need to create enterprise routers and enable Default Route Table Association and Default Route Table Propagation for them.

Creating a Central Network

2. Click in the upper left corner to select a region and a project.
3. In the service list, choose Network > Cloud Connect.
4. In the navigation pane on the left, choose Cloud Connect > Central Networks.
5. In the upper right corner of the page, click Create Central Network.
6. Enter the name and description and then configure policies for the central network. Table 1 describes the parameters required for creating a central network.

   Parameter	Setting
   Name	Enter a name for the central network.
   Description	Describe the central network for easy identification.
   Policy	Region Add a policy to record your configuration. You need to select a region for the policy. Enterprise Router Add only one enterprise router for a region. All added enterprise routers can communicate with each other by default. NOTE: Please select all the ERs which needs to be connected in one go in Create Central Network page. 10 kbit/s of bandwidth is provided for testing connectivity between enterprise routers.

7. Click OK.
