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. 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-segment-routing-extensions
Reviewer: John E Drake
Review Date: 19-June-2017
IETF LC End Date: 19-June-2017
Intended Status: Standards Track

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

Comments:
This document is clearly written and a model of brevity, although it assumes a certain familiarity with the topic of segment routing.

Major Issues:
No major issues found.

Minor Issues:
As recommended by the document shepherd, Acee Lindem, sections 6.1 and 6.2 should be removed because they lack an associated elements of procedure and apparently no one has implemented them.

Yours Irrespectively,

John
