CAUTION:
It is not required to make clients of a route reflector fully meshed. The route reflector forwards routing
information between clients. If clients are fully meshed, you can disable route reflection between
clients to reduce routing costs.
A cluster has only one route reflector, and the router ID is used to identify the cluster. You can
configure multiple route reflectors to improve network stability. In this case, you must specify the
same cluster ID for these route reflectors to avoid routing loops.
