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.
