Tom and Qin:

During the summer as an chair, I am a bit more flexible on the closing for
WGs.    This WG LC was to close by this week, but I will extended it 2 weeks
to allow two things to  happen: 
1) RTGWG to provide WG LC 
2) I2RS members to address Qin's changes to address Tom Petch's comments. 

Cheerily, Sue Hares

Not ready

The text says
    /*Consider udpating this part to make use of
draft-ietf-softwire-iftunnel*/ Well yes, consider it and come to a
conclusion otherwise I cannot see how this is ready to advance.
[Qin]: Good catch, will fix this. The idea is to align with RFC7224 and
reuse iana-interface-type.

The YANG module contains many references - good - but they are not in the
I-D references; again, not ready to advance.  I see



IANA considerations references RFC7950 - RFC 6020 is better here as all that
RFC7950 says is go see RFC6020.
[Qin]:Agree, will update based on your suggestion.


       This version of this YANG module is part of

       This version of this YANG module is part of
        "RFC XXXX: A YANG Data Model for Layer-2 Network Topologies"

You also have this unsuitable reference twice in the state module
The state module lacks references for the imports [Qin]:Fixed.
The state module description clause seems misleading; it is only the state
part of a module when NMDA is not supported.
Appendix A - is it Normative?  The customary convention is the Appendices
are not unless stated otherwise and there is no statement here.
[Qin]:No, will make this clear.
'An Example' does not use the addresses set aside for documentation
[Qin]:Good catch, will use RFC7042 recommended address range.
What is the closing date for this Last call?

Tom Petch
