You can delete network instance connections created in a transit router, such as virtual private cloud (VPC), Express Connect Router (ECR), VPN, and Cloud Connect Network (CCN) connections. Once deleted, the associated network will lose connectivity to other networks through the transit router.
VPC connections managed by cloud services
For VPC connections that are automatically created by cloud services, such as WUYING Workspace, and Cloud Firewall, you cannot delete them in the Cloud Enterprise Network (CEN) console. Log on to the corresponding service console to delete them.
Delete a network instance connection
Before deleting a VPC connection, ensure there are no routes associated with the VPC under the PrivateZone and Cloud Services tabs of the transit router details page. For details, see Disable access to PrivateZone and Disable access to a cloud service.
Skip the above step if you have added configurations for accessing PrivateZone and cloud services in the route table of an Enterprise Edition transit router.
