A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Inter-Domain Routing WG of the IETF.

        Title           : Deprecation of AS_SET and AS_CONFED_SET in BGP

   BCP 172 (i.e., RFC 6472) recommends not using AS_SET and
   AS_CONFED_SET in the Border Gateway Protocol.  This document advances
   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
   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.  This document (if approved) updates
   RFC 4271 and RFC 5065 by eliminating AS_SET and AS_CONFED_SET types,
   and obsoletes RFC 6472.
