Sorry, this cannot be the normal way. If a router receives an update from a
non-client with its own cluster-id (e.g. from another RR in the same
cluster) it should *drop* this update. Having no cluster configured is
totally wrong, especially if there are redundant RRs with iBGP sessions

Disbelieve :-) I would rather believe in my own folly.
