Usage
Information
When a BGP cluster contains only one route reflector, the cluster ID is the route
reflector’s router ID. For redundancy, a BGP cluster may contain two or more route
reflectors and you assign a cluster ID with the
bgp cluster-id
command.
Without a cluster ID, the route reflector cannot recognize route updates from the
other route reflectors within the cluster.
The default format for displaying the cluster-id is dotted decimal, but if you enter
the cluster-id as an integer, it displays as an integer.
