Abstract Abstract
BCP 172 (i.e., RFC 6472) recommends not using AS_SET and BCP 172 (i.e., RFC 6472) recommends not using AS_SET and
AS_CONFED_SET in the Border Gateway Protocol. This document advances AS_CONFED_SET in the Border Gateway Protocol. This document advances
this recommendation to a standards requirement in BGP; it proscribes this recommendation to a standards requirement in BGP; it proscribes
the use of the AS_SET and AS_CONFED_SET types of path segments in the 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 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. BGP and to make the semantics of the originator of a route clearer.
This will also simplify the design, implementation, and deployment of This will also simplify the design, implementation, and deployment of
