16.3.8 Route Reflection Example
In some ISP networks, the internal BGP mesh becomes quite large, and the IBGP full mesh does not scale well. For
such situations, route reflection provides a way to alleviate the need for a full IBGP mesh. In route reflection, the clients
peer with the route reflector and exchange routing information with it. In turn, the route reflector passes on (reflects)
information between clients.
The IBGP peers of the route reflector fall under two categories: clients and non-clients. A route reflector and its clients
form a cluster. All peers of the route reflector that are not part of the cluster are non-clients. The RS supports client
peers as well as non-client peers of a route reflector.
