The Border Gateway Protocol [1] is an inter-autonomous system routing protocol designed for TCP/IP internets. BGP deployments are configured such that that all BGP speakers within a single AS must be fully meshed so that any external routing information must be re- distributed to all other routers within that AS. This represents a serious scaling problem that has been well documented with several alternatives proposed [2,3].
This document describes the use and design of a method known as "Route Reflection" to alleviate the the need for "full mesh" IBGP.
