Name

bgp cluster-id — router, BGP

Synopsis

bgp cluster-id id
no bgp cluster-id id
            

Configures

Cluster ID of a route reflector

Default

Router ID

Description

This command specifies the cluster ID (id) for a BGP router. When you have one route reflector, its cluster ID is normally its router ID. If there is more than one route reflector in a cluster, they must all have the same cluster ID. In this case, you would use the bgp cluster-id command to specify the ID explicitly. A cluster ID is four bytes long.

Example

The following BGP configuration creates a BGP process for autonomous system 10. This router is designated as a route reflector. We set its cluster ID explicitly, because there is presumably more than one route reflector in the cluster.

router bgp 10
   network 10.200.200.1 route-reflector
   bgp cluster-id 10000
