                    draft-bgbw-opsawg-vpn-common-00

Abstract

   This document defines a common YANG module that is meant to be reused
   by various VPN-related modules such as Layer 3 VPN Service Model,
   Layer 2 VPN Service Model, Layer 3 VPN Network Model, and Layer 2 VPN
   Network Model.

1.  Introduction

   Various VPN-related YANG data modules were specified by the IETF
   (e.g., Layer 3 VPN Service Model (L3SM) [RFC8299] or Layer 2 VPN
   Service Model (L2SM) [RFC8466]).  Others are also being specified
   (e.g., Layer 3 VPN Network Model (L3NM) [I-D.ietf-opsawg-l3sm-l3nm]
   or Layer 2 VPN Network Model (L2NM) [I-D.ietf-opsawg-l2nm]).  These
   modules have data nodes and structures that are present in almost all
   these models or a subset of them.  An example of such data nodes is
   depicted in Figure 1.
