■ In general, since the route reflector forwards routing information between
clients, it is not required to make clients fully meshed. If clients are fully
meshed, it is recommended to disable route reflection between clients to
reduce routing costs.
■ If a cluster has multiple route reflectors, you need to specify the same cluster ID
for these route reflectors to avoid routing loops.
