BGP Route Reflection diagram

feature

I had plans to cover Nokia (Alcatel-Lucent) BGP Route Reflectors (BGP RR) in a full-featured post, but… But a lot of new stuff suddenly hit me as I joined Nuage Networks team.

Ok, lyrics aside, during my preparation for BGP exam I noticed that BGP route reflectors behavior defined throughout several chapters and there was no summary diagram (or cheatlist) that covered route reflectors decisions and actions. So, here you are:

This diagram shows the complete decision path of a BGP RR when it needs to reflect a route, including action items for different kind of neighbors (Non-client, Client, regular peer).

Note, that Nokia’s (Alcatel-Lucent) definitions were used for RIB structures (RIB-In, RIB-Out), though the decisions that RR has to make should no differ between vendors.
