Usage Information
A route reflector reflects routes to the neighbors assigned to the cluster. Neighbors in the cluster do not need not
to be fully meshed. By default, when you use no route reflector, the internal BGP (IBGP) speakers in the
network must be fully meshed.
The first time you enter this command, the router configures as a route reflector and the specified BGP neighbors
configure as clients in the route-reflector cluster.
When you remove all clients of a route reflector using the no neighbor route-reflector-client
command, the router no longer functions as a route reflector.
If the clients of a route reflector are fully meshed, you can configure the route reflector to not reflect routes to
specified clients by using the no bgp client-to-client reflection command.
This command automatically restarts the neighbor session for the configuration to take effect.
