There is one more rule:

Any route reflector that receives an iBGP update with its cluster-ID
already in the cluster-list will ignore that update.

This is mostly useful in configurations with redundant RRs, to prevent
routing loops between the RRs.

So on Juniper, how do I configure that iBGP peer x.x.x.x is not a
RR-client, but another RR in the same cluster as the current router?
