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.
