BGP Route Reflection

iBGP Route Reflection:
=====================

A route reflector can have three types of peers: EBGP peers, client peers, and nonclient
peers. EBGP peers are neighbors in a different AS number, including peers in
different Sub-ASs in confederation. Client peers are iBGP neighbors that have the
route-reflector-client statement configured. Non-client peers are normal iBGP
peers that do not have the route-reflector-client statement configured. Routing
advertisements sent from the route reflector must conform to the following three
rules:
1. Routes learned from EBGP peers can be sent to other EBGP peers, clients, and nonclients.
2. Routes learned from client peers can be sent to EBGP peers, other client peers, and
non-clients.
3. Routes learned from non-client peers can be sent to EBGP peers, and client peers,
but not other non-clients.
In the simplest of route-reflection designs, a central peering point is chosen for
