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-idr-bgp-ls-segment-routing-msd-05.txt
Reviewer: Mach Chen
Review Date: 10 September 2019
Intended Status: Standards Track

Summary:
I have some minor concerns about this document that I think should be resolved
before publication.

Comments:

Generally, I found the draft quite readable, with a clear explanation of the
problem statements and solutions. However, I have one minor comment and a nit.

Major Issues:

No major issues found.

Minor Issues:

This draft is an extension to BGP-LS (RFC 7752) that is under a re-spin, I have
a question whether this draft should reference to RFC 7752 or the new bis
document.

Nits:
1.1.1.  Terminology

Part of the last bullet should be separated into a dedicated paragraph, it
looks like an copy and pastes nit.

"The number of labels imposed is then the sum of the number of labels that are
      replaced and the number of labels that are pushed.  See [RFC3031]"

Best regards,
Mach
