IBPG

iBGP must be fully meshed because an iBGP speaker does not advertise the routes learned 
from another iBGP speaker to a third iBGP speaker. As a result, the total number of iBGP 
sessions among n iBGP routers is n(n-1)/2 sessions, and each router contains (n-1) 
sessions. To reduce the iBGP sessions, we can enable route refection (RR) for iBGP. In this 
example, we configure Switch A as the route reflector and Switches B and C as clients so 
that A, B, and C do not need to be fully meshed. This example shows only how to configure 
reflection. For the an example how to configure iBGP, see
