We use the term "Route Reflection" to describe the operation of a BGP

   speaker advertising an IBGP learned route to another IBGP peer.  Such

   a BGP speaker is said to be a "Route Reflector" (RR), and such a

   route is said to be a reflected route.

 

   The internal peers of an RR are divided into two groups:

 

      1) Client peers

 

      2) Non-Client peers

 

   An RR reflects routes between these groups, and may reflect routes

   among client peers.  An RR along with its client peers form a

   cluster.  The Non-Client peer must be fully meshed but the Client

   peers need not be fully meshed.  Figure 3 depicts a simple example

   outlining the basic RR components using the terminology noted above.

A route reflector (RR) is a network routing component for BGP (RFC 4456). It offers an alternative to the logical full-mesh requirement of internal border gateway protocol (IBGP). A RR acts as a focal pointfor IBGP sessions. The purpose of the RR is concentration.
