Route reflectors (RR) are used in BGP to reduce the number of iBGP sessions required within an Autonomous System (AS). Here are key points about route reflectors:
B. True: A route reflector can have both iBGP and eBGP clients, allowing it to propagate routes between internal and external peers.
C. True: A route reflector disables the iBGP split-horizon rule for its clients, allowing it to propagate routes received from one iBGP client to other iBGP clients.
D. True: Route reflectors reduce the number of iBGP sessions required in an AS by allowing clients to form iBGP sessions only with the route reflector instead of with every other iBGP peer.
The false statement is:
A. False: A full iBGP mesh is not required among route reflectors themselves. Instead, route reflectors can form a partial mesh or hierarchical structure to propagate routes efficiently.
