A YANG Model for MPLS MSD
draft-qu-mpls-mpls-msd-yang-00
Abstract
This document defines a YANG data module augmenting the IETF MPLS
YANG model to provide support for MPLS Maximum SID Depths (MSDs) as
defined RFC 8476 and RFC 8491.

1. Overview
YANG [RFC6020] [RFC7950] is a data definition language used to define
the contents of a conceptual data store that allows networked devices
to be managed using NETCONF [RFC6241]. YANG is proving relevant
beyond its initial confines, as bindings to other interfaces (e.g.,
ReST) and encodings other than XML (e.g., JSON) are being defined.
Furthermore, YANG data models can be used as the basis for
implementation of other interfaces, such as CLI and programmatic
APIs.
This document defines a YANG data module augmenting the IETF MPLS
YANG model [RFC8960], which itself augments [RFC8349], to provide
operational state for various MSDs[RFC8662].
The augmentation defined in this document requires support for the
MPLS base model[RFC8960] which defines basic MPLS configuration and
state.
The YANG module in this document conforms to the Network Management
Datastore Architecture (NMDA) [RFC8342].
1.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].

2. YANG Module for MPLS MSD
This document defines a YANG module for MSD extensions
[RFC8476][RFC8491] to MPLS base model as defined in [RFC8960].
