The IESG has approved the following document: - 'A YANG Network Data Model for Layer 2 VPNs' (draft-ietf-opsawg-l2nm-19.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-l2nm/ Technical Summary This document defines an L2VPN Network YANG Model (L2NM) which can be used to manage the provisioning of Layer 2 Virtual Private Network services within a network (e.g., service provider network). The L2NM complements the Layer 2 Service Model (L2SM) by providing a network- centric view of the service that is internal to a service provider. The L2NM is particularly meant to be used by a network controller to derive the configuration information that will be sent to relevant network devices. 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. Personnel Adrian Farrel (adrian@olddog.co.uk) is the Document Shepherd Rob Wilton (rwilton@cisco.com) iss the Responsible Area Director IESG Note This is the L2VPN version of the L3VPN equivalent (i.e., L3NM) that has been reviewed previously, alongside the common types definitions.
