           Gap Analysis for Operating IPv6-only MPLS Networks
                    draft-ietf-mpls-ipv6-only-gap-03

Abstract

   This document reviews the Multiprotocol Label Switching (MPLS)
   protocol suite in the context of IPv6 and identifies gaps that must
   be addressed in order to allow MPLS-related protocols and
   applications to be used with IPv6-only networks.  This document is
   not intended to highlight a particular vendor's implementation (or
   lack thereof) in the context of IPv6-only MPLS functionality, but
   rather to focus on gaps in the standards defining the MPLS suite.
