You can also include one of the following well-known community names (defined in RFC 1997, BGP Communities Attribute) in the community-ids option for the members statement:

no-advertise—Routes in this community name must not be advertised to other BGP peers.

no-export—Routes in this community must not be advertised outside a BGP confederation boundary.

no-export-subconfed—Routes in this community must not be advertised to external BGP peers, including peers in other members’ ASs inside a BGP confederation.
