Cross-Site Connection Bandwidths

Scenarios

Enterprise routers in different regions added to the same policy can communicate with each other after you purchase a global connection bandwidth and assign cross-site connection bandwidths for these network resources.

Constraints

• Changing Cross-Site Connection Bandwidth and Deleting a Cross-Site Connection Bandwidth cannot be performed when a cross-site connection is being created, updated, deleted, frozen, unfrozen, or is recovering.
• The total of cross-site connection bandwidths cannot exceed the global connection bandwidth.
• Cross site connection bandwidths are displayed only when a central network is created with at least 2 enterprise routers (1 per region) under policies.

Assigning a Cross-Site Connection Bandwidth

1. Log in to the management console.
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. Locate the central network and click its name.
6. Click the Cross-Site Connection Bandwidths tab.
7. Locate the cross-site connection and click Assign now in the Global Connection Bandwidth column.
8. On the Assign Bandwidth page, select the global connection bandwidth.

   You can also click create Now if there are no available global connection bandwidths.

9. Enter the bandwidth.
10. Click OK.

Viewing Monitoring Metrics of Cross-Site Connection Bandwidths

You can view the status of each cross-site connection bandwidth assigned for communication between network resources.

1. Log in to the management console.
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. Locate the central network and click its name.
6. Switch to the Cross-Site Connection Bandwidths tab and click the icon in the Monitoring column to view the monitoring data.

By setting up a central network, you can enable communications between enterprise routers in the same region or across regions. When a central network is used, attachments on the enterprise routers used in the central network policy will be monitored. For details about monitoring, see Central Network Metrics.

Changing Cross-Site Connection Bandwidth

1. Log in to the management console.
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. Locate the central network and click its name.
6. Click the Cross-Site Connection Bandwidths tab.
7. Locate the cross-site connection and click Change Bandwidth in the Operation column.
8. In the displayed dialog box, change the global connection bandwidth of the cross-site connection.

   You can also change the bandwidth of the cross-site connection.

9. Click OK.

Deleting a Cross-Site Connection Bandwidth

1. Log in to the management console.
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. Locate the central network and click its name.
6. Click the Cross-Site Connection Bandwidths tab.
7. Locate the cross-site connection and click Delete Bandwidth in the Operation column.
8. In the displayed dialog box, click OK.
   Figure 4 Deleting a cross-site connection bandwidth
   
9. Click Go to Delete to delete the global connection bandwidth if you no longer need it to avoid unnecessary charges.

After you delete a cross-site connection bandwidth, you still need to pay for the global connection bandwidth.
