    Cloud Enterprise Network (CEN) supports route advertisement. You can call this operation to advertise routes of virtual private clouds (VPCs) or virtual border routers (VBRs) attached to a CEN instance to the CEN instance. Other network instances attached to the CEN instance can learn the routes if route conflicts do not exist.

    Operation description

    The following table describes whether routes of different types are advertised to CEN by default. You can call the PublishRouteEntries operation to advertise routes to CEN.
