Re: BGP cluster-ID

 When using Route Reflectors, there is always a cluster-id associated
 with the RR and it's RR clients. If not configured explicitly, the
 router ID of the RR is used as the cluster-id. This ensures uniqueness
 between one RR cluster and another. If there are multiple RRs in the
 same cluster though, the cluster-id should be the same, and therefore
 the default RID needs to be overridden. This is the only way RR clients
 will know that both RRs are in the same cluster.

  So to answer your question succinctly, when you have multiple RR
 clusters in an AS, you do not need to configure the cluster-id, because
 it will automagically do it for you.
