The IESG has approved the following document: - 'A Layer 3 VPN Network YANG Model' (draft-ietf-opsawg-l3sm-l3nm-18.txt) as Proposed Standard This document is the product of the Operations and Management Area Working Group. The IESG contact persons are Warren Kumari and Robert Wilton. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-opsawg-l3sm-l3nm/ Technical Summary 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. Working Group Summary There was no controversy. This model was driven by implementers seeking to use the L3SM [RFC8309] to provide L3VPN services using orchestrator and controller software. They determined that an intermediary network-centric (rather than service-centric) model was required, and they quickly built support with other implementers. During the later stages of work on this document, it was determined that there was commonality between this model and a model for L2VPN. The common parts were pulled out into a separate model presented in another document. Document Quality This document notes four implementations: Nokia, Huawei, Infinera, Ribbon-ECI. The document shepherd is aware of one other commercial implementation and one prototype implementation.
