9.1 Route Reflectors
9.1.3 Internal peers with route reflectors
The RR acts as a concentration point, or route reflector server, for other routers called route reflector clients. The clients peer with the RR and exchange routing information with it. In turn, the RR will pass on (reflect) the information between clients.

In the Figure, RTA receives an update from an external peer and passes it on to RTC, which is configured as a RR with two clients, RTA and RTB. RTC will reflect the update from client RTA to client RTB.
