This document advances that recommendation to a standards requirement in BGP; it proscribes the use of the AS\_SET and AS\_CONFED\_SET path segment types 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 BGP route clearer. This will also simplify the design, implementation, and deployment of various BGP security mechanisms. This document updates RFC 4271 and RFC 5065, and obsoletes RFC 6472.}, }
