Usage 
Information
The first time you enter this command it configures the neighbor as a route reflector and 
members of the route-reflector cluster. Internal BGP (IBGP) speakers do not need to be fully 
meshed if you configure a route reflector.
When all clients of a route reflector are disabled, the neighbor is no longer a route reflector.
