Networking Requirements
As shown in
forwards the packet to Switch C. Switch C is configured as a route reflector and it has two clients,
namely, Switch B and Switch D.
Switch B and Switch D do not need to set up an IBGP connection. After receiving a route update
packet from Switch B, Switch C reflects the packet to Switch D. Similarly, after receiving a
route update packet from Switch D, Switch C reflects the packet to Switch B.
