Ballot Text

Technical Summary

   RFC 5492 allows a BGP speaker to advertise its capabilities to its
   peer.  When a route is propagated beyond the immediate peer, it is
   useful to allow certain characteristics to be conveyed further.  In
   particular, it is useful to advertise forwarding plane features.

   This specification defines a BGP transitive attribute to carry such
   information, the "Next Hop Dependent Characteristics Attribute," or
   NHC.  Unlike the capabilities defined by RFC 5492, the
   characteristics conveyed in the NHC apply solely to the routes
   advertised by the BGP UPDATE that contains the particular NHC.

Working Group Summary

   There was very good consensus on this document with several
   WG participants providing reviews and inputs from diverse
   backgrounds. There were two WGLC of the document due to the
   document split that was required due to IDR WGs need for
   implementations before publications. In both cases, there
   was good support for progressing this work.

Document Quality

   This document specifies a new BGP attribute the Next Hop
   dependent Characteristics (NHC). There are implementations
   of this new attribute for NHC TLVs specified in other
   IDR WG documents. These implementations are captured in the
   document as well as IDR wiki. The document has gone through
   early reviews by RTGDIR, SECDIR, and OPSDIR.

Personnel

   The Document Shepherd for this document is Susan Hares. The Responsible
   Area Director is Ketan Talaulikar.
