BGP CLUSTER ID

bgp cluster-id

Overview 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-id command 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.
bgp cluster-id {<ip-address>|<cluster-id>}
