Abstract

   Multi-protocol Label Switching - Transport Profile (MPLS-TP) is a
   profile of the MPLS protocol that is used in packet switched
   transport networks and operated in a similar manner to other
   existing transport technologies (e.g., OTN), as described in
   RFC5921. This document specifies YANG models for MPLS-TP, which have
   not been covered by existing models so far. The gap analysis with
   current relevant traffic-engineering (TE) and MPLS models is also
   included.

1. Introduction

   Multi-protocol Label Switching - Transport Profile (MPLS-TP) is a
   packet switching technology intended operated in a similar manner to
   other existing transport technologies (e.g., OTN), as described in
   [RFC5921], which includes Traffic Engineering (TE) features.

Internet-Draft               MPLS-TP YANG                    March 2019

   Generic TE models, including the TE topology and tunnel, have been
   defined in [TE-Topology] and [TE-Tunnel] using the YANG data
   modeling language and are applicable to any TE technologies
   including MPLS-TE and OTN and therefore also to MPLS-TP.

   The YANG models for MPLS with TE features (MPLS-TE), are provided in
   [TE-MPLS] as a technology-specific augmentations of the generic TE
