Hello,

I have been selected as the Routing Directorate reviewer for this draft.
The Routing Directorate seeks to review all routing or routing-related
drafts as they pass through IETF last call and IESG review, and
sometimes on special request. The purpose of the review is to provide
assistance to the Routing ADs. For more information about the Routing
Directorate, please see https://trac.ietf.org/trac/rtg/wiki/RtgDir
This is the second review from Routing Directorate.

Overall I think the draft is ready for publication but there a still
a few nits.

This review takes place in support of CCAMP working group last call.

Document: draft-ietf-ccamp-l1csm-yang-19
Reviewer: Nicolai Leymann
Review Date: 09 December 2022
IETF LC End Date: Not yet started
Intended Status: Draft Standard

Nits:
either "Layer 1" or "layer 1" should be used consistently throughout the document:
- Page 5, First sentence:
  "The benefit is that the same layer 1 transport network resources are"
- Page 6, 
  "The L1CSM YANG data model describes the layer 1 connectivity services"
References to "RFCXXX", "RFC XXX" and "RFCYYY" need to be fixed.
- (In some cases there is a comment that this needs to be updated but not not in all cases. E.g., Page 9)

Page 6, Table has no caption, References need to be fixed ("RFCXXX"/"[RFCYYY]")

Some of the comments from Adrians review (e.g., use of "P" as Protcol but also
in different context in Figues are not addressed (yet)).
