9.18.2 Example for Configuring a BGP4+ Route Reflection

A BGP4+ route reflector avoids fully meshed connections between IBGP peers and therefore
simplifies the network.
Networking Requirements
As shown in
it to Router C. Router C is configured as a route reflector with two clients, Router B and Router
D.
Router B and Router D need not set up an IBGP connection. When Router C receives the route
update packet from Router B, it reflects the information to Router D. Similarly, when Router C
receives the route update packet from Router D, it reflects the information to Router B.
