Configuring An Mbgp Route Reflector - HP A8800 Configuration Manual

Configuring an MBGP route reflector

To guarantee the connectivity between multicast IBGP peers in an AS, you need to make them fully
meshed. But this becomes unpractical when large numbers of multicast IBGP peers exist. Configuring
route reflectors can solve this problem.
In general, it is not required that clients of a route reflector be 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.
In general, a cluster has only one route reflector, and the router ID of the route reflector identifies the
cluster. You can configure multiple route reflectors to improve network stability. In this case, you need to
specify the same cluster ID for these route reflectors to avoid routing loops.
To configure an MBGP route reflector:
Step
1. Enter system view.
2. Enter BGP view.
3. Enter IPv4 MBGP address
family view.
4. Configure the router as a
route reflector and specify an
MBGP peer/peer group as its
client.
5. Enable route reflection
between clients.
6. Configure the cluster ID of the
route reflector.
