              MPLS Transport Profile (MPLS-TP) Identifiers
                      Following ITU-T Conventions

Abstract

   This document specifies an extension to the identifiers to be used in
   the Transport Profile of Multiprotocol Label Switching (MPLS-TP).
   Identifiers that follow IP/MPLS conventions have already been
   defined.  This memo augments that set of identifiers for MPLS-TP
   management and Operations, Administration, and Maintenance (OAM)
   functions to include identifier information in a format typically
   used by the International Telecommunication Union Telecommunication
   Standardization Sector (ITU-T).

1.  Introduction

   This document augments the initial set of identifiers to be used in
   the Transport Profile of Multiprotocol Label Switching (MPLS-TP)
   defined in [RFC6370] by adding new identifiers based on ITU-T
   conventions.  It is not intended that both types of identifiers will
   be used at the same time in the same domain.
