Two more YANG quirks, belatedly.
s.7.6 has
| +--:(evpn-bgp)
| +--rw df-preference? uint16
| +--rw vpws-service-instance
while s.7.6.2 has
| +--:(evpn-bgp)
| +--rw vpws-service-instance
df-preference is present in the YANG module so I think that the approach
in s.7.6 is preferable to that of s.7.6.2.
s.7.5.2 has
+--rw (signaling-option)? choice
| +--:(bgp) case
| | ... choice bgp-type
| +--:(ldp-or-l2tp) case
so I expect to see
choice signaling-option which I do on page 87
case bgp also on page 87
....
case ldp-or-l2tp nowhere to be seen.
In fact, there is no case, rather there is a container with that
identifier on page 93. This is valid YANG - a container can stand in
for a case - but with six pages of YANG in-between, this is hard to
follow. I would suggest /container/case/ or if there is a reason for
not using case, then add a comment to that effect in the YANG module
prior to the container statement.

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@xxxxxxxx mailing lists by 2022-05-13. Exceptionally, comments may
be sent to iesg@xxxxxxxx instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.
Abstract
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.
Also, this document defines a YANG module to manage Ethernet segments
and the initial versions of two IANA-maintained modules that defines
a set of identities of BGP Layer 2 encapsulation types and pseudowire
types.
