To delete a cluster ID, use the no bgp cluster-id {ip-address | number} command.
Parameters

Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
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.
