Usage Information
When a BGP cluster contains only one route reector, the cluster ID is the route reector’s router ID. For
redundancy, a BGP cluster may contain two or more route reectors. Assign a cluster ID with the bgp cluster-
id command. Without a cluster ID, the route reector cannot recognize route updates from the other route
reectors 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 conguration to take eect.
