Cloud Enterprise Network (CEN) supports route withdrawal. You can withdraw routes that are advertised to a CEN instance. After a route is withdrawn from CEN, network instances attached to the CEN instance cannot learn this route. If a custom route is advertised to a CEN instance and the custom route is deleted from a virtual private cloud (VPC) or a virtual border router (VBR), the custom route is also deleted from the CEN instance.
Background information
Note The CEN console allows you to withdraw only VPC routes. To withdraw VBR routes, you
must call the WithdrawPublishedRouteEntries API operation. For more information, see
WithdrawPublishedRouteEntries.
