136 CHAPTER 5: ROUTING PROTOCOL OPERATION
Configuring BGP Route Reflector
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.
