This topic describes how to withdraw a route from Cloud Enterprise Network (CEN). You can withdraw a route that has been published to CEN. After the route is withdrawn, other networks attached to the same CEN instance cannot learn the route. If you publish a custom VPC or Virtual Border Router (VBR) route entry to a CEN instance and then delete the route from the VPC or VBR route table, the route entry is also deleted from CEN.

Background information

The following table lists the route entries that can be withdrawn from CEN.
Note Currently, the console only supports withdrawing VPC routes from CEN. If you need to withdraw VBR routes, call WithdrawPublishedRouteEntries. For more information, see WithdrawPublishedRouteEntries.
