Early Review of draft-ietf-idr-as-migration-05
review-ietf-idr-as-migration-05-rtgdir-early-morin-2015-06-04-00

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)
