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 SSR supports client peers as well as non-client peers of a
route reflector.
