Configuration of Pro-Active Operations, Administration, and Maintenance
    (OAM) Functions for MPLS-based Transport Networks using RSVP-TE
              draft-ietf-ccamp-rsvp-te-mpls-tp-oam-ext-12

Abstract

   This specification describes the configuration of pro-active MPLS-TP
   (MPLS-Transport Profile) Operations, Administration, and Maintenance
   (OAM) Functions for a given LSP using a set of TLVs that are carried
   by the GMPLS RSVP-TE protocol based on [OAM-CONF-FWK].

   This document is a product of a joint Internet Engineering Task Force
   (IETF) / International Telecommunication Union Telecommunication
   Standardization Sector (ITU-T) effort to include an MPLS Transport
   Profile within the IETF MPLS and PWE3 architectures to support the
   capabilities and functionalities of a packet transport network.
