IPv6 BGP Route Reflector
Configuration
Network requirements
Switch B receives an EBGP update and sends it to Switch C, which is configured as
a route reflector with two clients: Switch B and Switch D.
Switch B and Switch D need not establish an IBGP connection because Switch C
reflects updates between them.
