                    A Layer 2 VPN Network Yang Model
                   draft-barguil-opsawg-l2sm-l2nm-01

Abstract

   This document defines a YANG Data model (called, L2NM) that can be
   used to manage the provisioning of Layer 2 VPN services within a
   Service Provider Network.  This YANG module provides representation
   of the Layer 2 VPN Service from a network standpoint.  The module is
   meant to be used by a Network Controller to derive the configuration
   information that will be sent to relevant network devices.

   The L2SM complements the Layer 2 Service Model (RFC8466) by providing
   a network-centric view of the service that is internal to a Service
   Provider.
