                    A YANG Data Model for MPLS Base
                      draft-ietf-mpls-base-yang-06

Abstract

   This document contains a specification of the the MPLS base YANG
   model.  The MPLS base YANG module serves as a base framework for
   configuring and managing an MPLS switching subsystem.  It is expected
   that other MPLS technology YANG models (e.g.  MPLS LSP Static, LDP or
   RSVP-TE models) will augment the MPLS base YANG model.

1.  Introduction

   A core routing data model is defined in [RFC8022], and it provides a
   basis for the development of data models for routing protocols.  The
   MPLS base model augments this model with additional data specific to
   MPLS switching [RFC3031].  The interface data model is defined in
   [RFC7223] and is used for referencing interface from the MPLS base
   model.

   The MPLS base YANG module augments the "routing" read-write (rw) and
   "routing-state" read-only (ro) branches of the ietf-routing module
   defined in [RFC8022].

   This document defines the specification for the "ietf-mpls" YANG
   module that provides base components of the MPLS data model.  It is
   expected that other MPLS YANG modules will augment the "ietf-mpls"
   base model to define data models for other MPLS technologies (e.g.
   MPLS LDP or MPLS RSVP-TE).

   This document also defines a way to model MPLS labelled routes as an
   augmentation of the the routing RIB model defined in [RFC8022] for IP
   prefix routes that are MPLS labelled.  Other MPLS non-IP prefix
   routes are also modelled by introducing a new "mpls" address-family
   RIB.
