         A YANG Data Model for MPLS Traffic Engineering Tunnels
                    draft-ietf-teas-yang-te-mpls-01

Abstract

   This document defines a YANG data model for the configuration and
   management of Multiprotocol Label Switching (MPLS) Traffic
   Engineering (TE) tunnels, Label Switched Paths (LSPs) and interfaces.
   The model augments the TE generic YANG model for MPLS packet
   dataplane technology.

   This model covers data for configuration, operational state, remote
   procedural calls, and event notifications.

1.  Introduction

   YANG [RFC6020] and [RFC7950] is a data modeling language used to
   define the contents of a conceptual data store that allows networked
   devices to be managed using NETCONF [RFC6241].  YANG has proved
   relevant beyond its initial confines, as bindings to other interfaces
   (e.g.  RESTCONF [RFC8040]) and encoding other than XML (e.g.  JSON)
   are being defined.  Furthermore, YANG data models can be used as the
   basis of implementation for other interfaces, such as CLI and
   programmatic APIs.

   This document describes the YANG data model for configuration and
   management of MPLS TE tunnels, LSPs, and interfaces.  Other YANG
   module(s) that model the establishment of MPLS LSP(s) via signaling
   protocols such as RSVP-TE ([RFC3209], [RFC3473]) are described in
   separate document(s).

1.1.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
