5.4.2 Configuring BGP Route Reflector
I. Networking requirements
Switch B receives an update packet passing EBGP and transmits it to Switch C. Switch
C is a reflector with two clients: Switch B and Switch D. When Switch C receives a route
update from Switch B, it will transmit such information to Switch D. It is required to
establish an IBGP connection between Switch B and Switch D, because Switch C
reflects information to Switch D.
