A YANG Data Model for MPLS Base
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
data models) will augment the MPLS base YANG data model.

1. Introduction
A core routing YANG data model is defined in [RFC8349]; 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 AF agnostic.
[RFC8349] also defines two instances of RIBs based on the generic RIB
model for IPv4 and IPv6 AFs.
The MPLS base model defined in this document augments the generic RIB
model defined in [RFC8349] with additional data that enables MPLS
forwarding for one or more specific destination prefixes present in
one or more AF RIBs, 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.
The native MPLS RIB instance stores one or more routes that are not
associated with other AF instance RIBs (such as IPv4 or IPv6 instance
RIBs) but are enabled for MPLS forwarding. Examples of such native
MPLS routes are routes programmed by RSVP on one or more transit MPLS
routers along the path of a Label Switched Path (LSP). Other
examples are MPLS routes that cross-connect to specific Layer 2
adjacencies, such as Layer 2 Attachment Circuits (ACs); or Layer 3
adjacencies, such as Segment Routing (SR) Adjacency Segments (Adj-
SIDs) as described in [RFC8402].
The MPLS base YANG data model serves as a basis for future
development of MPLS YANG data models covering MPLS features and
subsystems that are more sophisticated. The main purpose is to
provide essential building blocks for other YANG data models
involving different control-plane protocols and MPLS functions.
To this end, it is expected that the MPLS base data model will be
augmented by a number of other YANG modules developed by the IETF
(e.g., by the TEAS and MPLS Working Groups).
The YANG module defined in this document conforms to the Network
