Route Reflectors
Only the best path is propagated
From an eBGP peer, send the path to everyone
From a RRC, reflect the path to clients and non-clients, send the path to eBGP peers
From a regular iBGP peer (non-client), reflect the path to RRCs and send the path to eBGP peers
When a route is reflected the RR appends its ROUTER_ID (or configured bgp cluster-id) to the CLUSTER_LIST
