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.
