Configuring a cluster ID for a route reflector

The cluster ID can be changed if there is more than one route reflector, so that all route reflectors belong to the same cluster.
  1. Enter the configure terminal command to access global configuration mode.
    device# configure terminal
  2. Enter the router bgp command to enable BGP routing.
    device(config)# router bgp
  3. Enter the local-as command to configure the autonomous system number (ASN) in which your device resides.
    device(config-bgp-router)# local-as 1000
  4. Enter the cluster-id command and specify a value to change the cluster ID of a device from the default device ID.
    device(config-bgp-router)# cluster-id 321

The following example changes the cluster ID of a device from the default device ID to 321.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# cluster-id 321
