Configure a Cluster ID for a BGP4 Route Reflector

When you have more than one route reflector, change the cluster ID so that all route reflectors belong to the same cluster.

About this task

Multiple route reflectors should belong to the same cluster. By default, the value for the cluster-id command is the device ID. Use this procedure to change the device ID.

Procedure

  1. Access global configuration mode.
    device# configure terminal
  2. Access BGP configuration mode.
    device(config)# router bgp
  3. Specify the autonomous system in which your device resides.
    device(config-bgp-router)# local-as 1000
  4. Change the device ID.
    device(config-bgp-router)# cluster-id 321
    This example changes the cluster ID of a device from the default value to 321.

Example

The following example summarizes the commands in this procedure.
device# configure terminal
device(config)# router bgp
device(config-bgp-router)# local-as 1000
device(config-bgp-router)# cluster-id 321
