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. 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.
This command automatically restarts the BGP instance for the configuration to take effect.
