               YANG Data Model for L3VPN Service Delivery

Abstract

   This document defines a YANG data model that can be used for
   communication between customers and network operators and to deliver
   a Layer 3 provider-provisioned VPN service.  This document is limited
   to BGP PE-based VPNs as described in RFCs 4026, 4110, and 4364.  This
   model is intended to be instantiated at the management system to
   deliver the overall service.  It is not a configuration model to be
   used directly on network elements.  This model provides an abstracted
   view of the Layer 3 IP VPN service configuration components.  It will
   be up to the management system to take this model as input and use
   specific configuration models to configure the different network
   elements to deliver the service.  How the configuration of network
   elements is done is out of scope for this document.
