When you do not need to use Express Connect to connect two VPCs (VPC-A and VPC-B are used in this tutorial), you can delete the route interfaces used for interconnecting the two VPCs to remove the interconnection.

Step 1: Delete route entries

Follow these steps to delete the route entry pointing to the other VPC in each VPC:

  1. Log on to the Express Connect console.
  2. Select the region where VPC-A is located.
  3. Click Manage in the Actions column of VPC-A.
  4. In the left-side navigation pane, click VRouters.
  5. Find the route entry of which the destination CIDR block is the CIDR block of VPC-B and the next hop type is router interface and click Delete in the Actions column. Click Confirm in the displayed dialog box.
  6. Repeat the preceding steps to delete the route entry of VPC-B used to connect to VPC-A.

Step 2: Freeze and delete router interfaces

Follow these steps to freeze and delete two interconnected router interfaces:

  1. Log on to the Express Connect console.
  2. In the left-side navigation pane, click Router Interface.
  3. Select the region where VPC-A is located.
  4. Find the router interface of VPC-A used to connect to VPC-B, and click Freeze in the Actions column.
  5. When the status of the router interface changes from Activated to Frozen, click More > Delete in the Actions column. Click Confirm in the displayed dialog box.
  6. Repeat the preceding steps to delete the router interface of VPC-B used to connect to VPC-A.
Note
  • A frozen router interface will still be billed. A router interface will not be billed only when it is deleted.
  • If there still is any route entry pointing to the router interface, the router interface cannot be deleted.
