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.

IESG Note
This is the L2VPN version of the L3VPN equivalent (i.e., L3NM) that has been reviewed previously, alongside the common types definitions.
