8.15.2 Example for Configuring BGP4+ Route Reflectors
Networking Requirements
As shown in Figure 8-2, Switch B receives an update packet from Switch A through EBGP and
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.

Configuration Roadmap
The configuration roadmap is as follows:
1. Establish IBGP connections between the clients and the route reflector.
2. Configure Switch C as the route reflector.
