bgp cluster-id — router, BGP
idno bgp cluster-id
Cluster ID of a route reflector
This command specifies the cluster ID (
id) for a BGP router. When you have one route reflector, its cluster ID is normally its router ID. If there is more than one route reflector in a cluster, they must all have the same cluster ID. In this case, you would use the
bgp cluster-id command to specify the ID explicitly. A cluster ID is four bytes long.
The following BGP configuration creates a BGP process for autonomous system 10. This router is designated as a route reflector. We set its cluster ID explicitly, because there is presumably more than one route reflector in the cluster.
