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.

Abstract and Introduction

s/In this document we propose/This document defines


Introduction

s/"Send-update Process"/Send-update Process, to align with the usage as in RFC4271.

Section 4

"Send/Receive:

         This field indicates whether the sender is (a) able to receive
         multiple paths from its peer (value 1), (b) able to send
         multiple paths to its peer (value 2), or (c) both (value 3) for
         the <AFI, SAFI>."

How about other values and what's the process when received value other than 1, 2 and 3?

   UPDATE message for a particular <AFI, SAFI> to a peer unless the BGP..."

   UPDATE message for a particular <AFI, SAFI> to a peer unless the BGP..."
