    abstract =  {As a complement to the Layer 3 Virtual Private Network Service YANG data Model (L3SM), used for communication between customers and service providers, this document defines an L3VPN Network YANG Model (L3NM) that can be used for the provisioning of Layer 3 Virtual Private Network (VPN) services within a service provider 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.},
