                    A Layer 3 VPN Network YANG Model
                     draft-ietf-opsawg-l3sm-l3nm-03

Abstract

   This document defines a L3VPN Network YANG Model (L3NM) that can be
   used to manage the provisioning of Layer 3 Virtual Private Network
   (VPN) services within a Service Provider's network.  The model
   provides a network-centric view of L3VPN services.

   L3NM is meant to be used by a Network Controller to derive the
   configuration information that will be sent to relevant network
   devices.  The model can also facilitate the communication between a
   service orchestrator and a network controller/orchestrator.

   L3NM focuses on BGP PE-based Layer 3 VPNs as described in RFCs 4026,
   4110 and 4364 and Multicast VPNs as described in RFCs 6037, 6513 and
   7988.

Editorial Note (To be removed by RFC Editor)

   Please update these statements within the document with the RFC
   number to be assigned to this document:

   o  "This version of this YANG module is part of RFC XXXX;"

   o  "RFC XXXX: Layer 3 VPN Network Model";

   o  reference: RFC XXXX

   Also, please update the "revision" date of the YANG module.
