                 A YANG Data Model for MPLS Static LSPs
                     draft-ietf-mpls-static-yang-07

Abstract

   This document contains the specification for the MPLS Static Label
   Switched Paths (LSPs) YANG model.  The model allows for the
   provisioning of static LSP(s) on LER(s) and LSR(s) devices along a
   LSP path without the dependency on any signaling protocol.  The MPLS
   Static LSP model augments the MPLS base YANG model with specific data
   to configure and manage MPLS Static LSP(s).

1.  Introduction

   This document describes a YANG [RFC7950] data model for configuring
   and managing the Multiprotocol Label Switching (MPLS) [RFC3031]
   Static LSPs.  The model allows the configuration of LER and LSR
   devices with the necessary MPLS cross-connects or bindings to realize
   an end-to-end LSP service.

   A static LSP is established by manually specifying incoming and
   outgoing MPLS label(s) and necessary forwarding information on each
   of the traversed Label Edge Router (LER) and Label Switched Router
   (LSR) devices (ingress, transit, or egress nodes) of the forwarding
   path.

   For example, on an ingress LER device, the model is used to associate
   a specific Forwarding Equivalence Class (FEC) of packets- e.g.
