Cloud Enterprise Network:DeleteCenChildInstanceRouteEntryToAttachment

Last Updated:Mar 25, 2024

Deletes a route of a network instance from an Enterprise Edition transit router.

Operation description

  • You can delete routes only from virtual private clouds (VPCs) and virtual border routers (VBRs) whose next hop is an Enterprise Edition transit router connection, which is the connection to the network instance.

  • DeleteCenChildInstanceRouteEntryToAttachment is an asynchronous operation. After you send a request, the system returns a request ID and runs the task in the background. You can call the DescribeRouteEntryList operation to query the status of a route.

    • If a route is in the Deleting state, the route is being deleted. You can query the route but cannot perform other operations.
    • If a route cannot be found, the route is deleted.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
