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 will be displayed as an integer.
