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 
​http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir

Although these comments are primarily for the use of the Routing ADs, it would 
be helpful if you could consider them along with any other IETF Last Call 
comments that you receive, and strive to resolve them through discussion or by 
updating the draft.

Document: draft-ietf-ospf-yang-23.txt
Reviewer: Ravi Singh
Review Date: 7/18/2019
Intended Status: Standards Track

Summary:
This document is basically ready for publication, but has nits that should be 
considered prior to publication.

This is a very comprehensively written document.
However, reading through it is a bit laborious due to the really large # of 
config and operational items described.
So, my review was primarily aimed at readability rather than correctness of the 
YANG syntax.

Specific comments/queries:
1.       What is the reasoning for sticking the multi-topology sub-container(s) 
at the same levels as area instead of at the level of sub-containers under 
area(s)?

OSPF Multi-Topology is not a widely deployed feature and that is why we did it 
with augmentations. I’ve removed the area list from the instance level 
augmentation and added a separate augmentation at the area level. This change 
will be in the -24 version.

2.       Pg 23: why both (prefix "rt-types";) and (prefix "iana-rt-types";) ?
They are two separate models in the RFC 8294. The latter module is maintained 
by IANA.

3.       Pg 25-28: "feature two-part-metric {" and "feature key-chain {" might 
be readjusted in order of listing to make it the same as that in section 2.4 
for a bit of enhanced readability.

I agree. However, I’ve removed two-part metric and it will be in the 
augmentation draft.

Thanks,
Acee

Regards
Ravi
