route to other iBGP speakers because the routers do not pass on routes learned from internal neighbors to
other internal neighbors, thus preventing a routing information loop.
Figure 6: Three Fully Meshed iBGP Speakers
With route reflectors, all iBGP speakers need not be fully meshed because there is a method to pass learned
routes to neighbors. In this model, an iBGP peer is configured to be a route reflector responsible for passing
iBGP learned routes to a set of iBGP neighbors. In Figure 7: Simple BGP Model with a Route Reflector, on
page 49 , Router B is configured as a route reflector. When the route reflector receives routes advertised from
