BGP and BGP4+ Commands

bgp cluster-id (BGP and BGP4+)

This command configures the cluster-id if the BGP cluster has more than one route reflector. A cluster includes one or more route reflectors and their clients. Usually, each cluster is identified by the router-id of its single route reflector. However, to increase redundancy, a cluster may sometimes have more than one route reflector. All router reflectors in such a cluster are then identified by a cluster-id.

The bgp cluster-idcommand is used to configure the 4 byte cluster ID for clusters with more than one route reflector.

The no variant of this command removes the cluster ID.
