Hello,

In the context of Routing Area QA reviews (see 
https://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDirDocQa ), 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.

//// Note well: this review comes as a complement to a first review I 
did last September. ////


Document: http://tools.ietf.org/html/draft-ietf-idr-as-migration-05
Reviewer: Thomas Morin
Review Date: 2015-06-02
Intended Status: standards track

*Summary:* This document is I think ready for publication.

*Comments:*

This is overall a very well written document, with a clear goal and 
addressing its target goal.

Although it is all about local behavior, it makes sense to make a 
standard track document that (a) can be used as a reference for 
implementors and deployers to implement this properly, and (b) keep 
track of these features in future evolutions of the protocol (as 
motivated in the Conclusion section of the document).

The document has taken into account my comments made on -02, and has 
gone to additional changes that bring significant improvements to the 
document.

*Major Issues:*  No major issues found

*Minor Issues:*

- it sounds weird to name "customer C" the customer attached to ISP B, 
not naming it, or naming it CE-B would better match figures 4 and 5
- figures 1 and 2 could be left-right reversed to match fig 4 and 5
- "are service interrupting to the eBGP sessions of the PE", maybe could 
be worded as "result in a service interruption of eBGP sessions of the 
PE" ?  (or, at least,  "service-interrupting", with a dash)
