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 is displayed as an integer.
