We have posted the updated version ( ) to fix the issues that you raised.
Thanks a lot,


looks better and apologies for being slow to respond.

C.12 IANA, C.13 Security look odd and contradict s.5, s.6.  Is there any reason for them to exist?

Security s.6 does not conform to the boiler plate referenced in RFC8407.  This asks that sensitive nodes be called out and I would think that at least the enable nodes for connectivity matrix and link terminations would qualify for that.

Some quirks.

Introduction/Abstract do not mention support or lack thereof  for NMDA
(which the IESG have been calling for).
[Xufeng]: Added.

Introduction does not have a reference for YANG leaving the question of
version number uncertain
[Xufeng]: Added.

Terminology fails to reference RFC8174
[Xufeng]: Fixed

Expand on first use, perhaps in Terminology, is helpful - TOSCA, SF2LTP,
[Xufeng]: Fixed

[Xufeng]: Authors and contributors discussed CSO and decided to remove it from this document and put it into a separate document.

yang-version 1 is rather limiting
[Xufeng]: Use 1.1 now.

YANG import statements lack references (which YANG 1.1 allows)

/       reference "TBD";/
       reference "RFC XXXX - SF Aware TE Topology YANG Model"; /
[Xufeng]: Fixed these statements.

   module ietf-cso-dc
no version
no copyright
no reference to the I-D
no description clauses
no reference clauses
somewhat short of ready IMHO- I think that this needs a lot of work!
[Xufeng]: As mentioned above, CSO is removed from this document and planned to be put into a separate document.

IANA Considerations
   RFC Ed.: In this section, replace all occurrences of 'XXXX' with the
   actual RFC number (and remove this note).
I suggest that this apply throughout the I-D and that the Note is placed
at the start, before the Introduction (the RFC Editor are happy with
just the one note)
[Xufeng]: Changed as suggeted.

RFC6020 is a better reference for the IANA Considerations
[Xufeng]: Right. Use  RFC6020 now.

[Xufeng]: Fixed.

[Xufeng]:  Fixed.

[Xufeng]: Fixed.

     import ietf-actn-vn {
does not appear in section 1.3
[Xufeng]: Added.
