Configuring a BGP route reflector

If an AS has many BGP routers, you can configure them as a cluster and configure one of them as a
route reflector and others as clients to reduce IBGP connections.
To enhance network reliability and prevent single point of failure, specify multiple route reflectors for
a cluster. The route reflectors in the cluster must have the same cluster ID to avoid routing loops.
In general, 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, disable route reflection
between clients to reduce routing costs.
