BCP 172 (i.e., RFC 6472) recommends not using AS_SET and AS_CONFED_SET in Border Gateway Protocol (BGP). This document updates RFC 4271 and proscribes the use of the AS_SET and AS_CONFED_SET types of path segments in the AS_PATH. This is done to simplify the design and implementation of BGP and to make the semantics of the originator of a route clearer. This will also simplify the design, implementation, and deployment of various BGP security mechanisms.
