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.
