This lesson in Russ White’s BGP course delves into synchronization within an Autonomous System (AS) and confederation within an AS. It also discusses route reflectors, including how they prevent loops, route reflector clients, route reflector multi-path, and multi-path pros and cons. Russ White is a network architect, author, and instructor. You can subscribe to the […]

BGP Route Reflector in Plain English, in this post, I will explain you the BGP Route Reflector basics, after you read this post, you will be able to answer many questions regarding BGP Route Reflectors.
Outline of this post is as below.
To have a great understanding of SP Networks, you can check my new published “Service Provider Networks Design and Perspective” Book. It covers the SP network Technologies with also explaining in detail a factious SP network. Click here
What is BGP Route Reflector ?
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).
Above is the wikipedia definition of BGP Route Reflector. Let’s extend the definition a bit.

BGP Route Reflection solves a fundamental problem in iBGP operation but introduces some tradeoffs to consider when implementing. In this Network Collective short take, Russ details these tradeoffs and some potential ways to mitigate unintended consequences.
BGP Route reflectors are used as an alternate method to full mesh IBGP and helps for scaling. BGP Route reflector clustering is used to provide redundancy in an RR design. Route Reflectors and its clients create a cluster. In an IBGP topologies, every BGP speaker has to be in a logically full mesh. Route reflectors… Read More »
