Deleting a Peering Connection Attachment

Scenarios

If a peering connection attachment is no longer required, you can delete it at any time.

Constraints

• Deleting an attachment will also delete its associations, propagations, and propagated routes from the route tables. As a result, the corresponding network instance cannot communicate with other network instances through the enterprise router. Exercise caution when performing this operation.
• If an attachment is deleted, the next hop of its related static routes will be Blackhole. If the destination of a packet matches the blackhole route, the packet will be discarded.
• If an attachment is associated with a flow log, the flow log will be deleted, but collected logs will not be deleted.

Procedure

1. Go to the enterprise router list.
2. Search for the target enterprise router by name.
3. Go to the Attachments tab using either of the following methods:
   • In the upper right corner of the enterprise router, click Manage Attachment.
   • Click the enterprise router name and click Attachments.
   You can view the name of a peering connection attachment on the Attachments tab.

   

   A peering connection attachment cannot be directly deleted on the Attachments tab.

   To delete such a peering connection attachment, you need to go to the Cloud Connect console, choose Central Networks to delete the peering connection attachment, change policies, and delete unnecessary policies. Deleting unnecessary policies will also delete the peering connection attachments. For details, see Deleting a Policy.
