BGP Confederations - inner workings
I feel as if I have a pretty good understanding of what a confederation is and where it might be appliacble. However, I don't understand the in-depth workings of BGP in relation to confederations. What is the router actually doing? What do the "bgp confederation indentifier" and "bgp confederation peers" actual do from a router perspective? Is it a completely seperate code-path in the handling of confederations or is there just additional fields and behaviors within a confederation?
