Configuring an IPv6 BGP route reflector

Follow these guidelines when you configure an IPv6 BGP route reflector:

In general, because the route reflector forwards routing information between clients, you are not
required to make clients of a route reflector fully meshed. If clients are fully meshed, H3C

recommends that you disable route reflection between clients to reduce routing costs.

If a cluster has multiple route reflectors, you must specify the same cluster ID for these route reflectors
to avoid routing loops.
