                    A YANG Data Model for MPLS Base
                      draft-ietf-mpls-base-yang-17

Abstract

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

1.  Introduction

   A core routing YANG data model is defined in [RFC8349], and it
   provides a basis for the development of routing data models for
   specific Address Families (AFs).  Specifically, [RFC8349] defines a
   model for a generic Routing Information Base (RIB) that is Address-
   Family (AF) agnostic.  [RFC8349] also defines two instances of RIBs
   based on the generic RIB model for IPv4 and IPv6 AFs.

   The MPLS base model that is defined in this document augments the
   generic RIB model defined in [RFC8349] with additional data that
   enables MPLS forwarding for the specific destination prefix(es)
   present in the AF RIB(s) as described in the MPLS architecture
   document [RFC3031].

   The MPLS base model also defines a new instance of the generic RIB
   YANG data model as defined in [RFC8349] to store native MPLS routes.
