Y'all --

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 ‚Äč

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.

draft more readable below.


1.  Introduction

   Routers that form the internet routing infrastructure maintain state
   at various layers of detail and function.  For example, a typical
   router maintains a Routing Information Base (RIB), and implements
   routing protocols such as OSPF, ISIS, and BGP to exchange protocol
   state and other information about the state of the network with other

   This is a bit of a quibble, but... While routing protocols do exchange
   "protocol state and other information about the state of the network," The
   primary point of routing protocols is to exchange reachability and topology
   information -- which seems to be included in the "other information"
   category here. Just seems strange to put the primary reason behind the
   protocols into the "other information" category. :-)


5.  Network Applications and I2RS Client

   In the simplest architecture, a network-oriented application has an
   I2RS client as a library or driver for communication with routing

   It just feels a little odd to have one named interaction type, and two
   unnamed ones (?). I'm going to suggest ideas here, though it's not a crucial
   point either way, since these aren't referred to anyplace else.

   Perhaps the "direct access architecture."


   In a third architecture, a routing element or network-oriented
   application that uses an I2RS Client to access services on a
   different routing element may also contain an I2RS agent to provide
   services to other network-oriented applications.  However, where the
   needed information and data models for those services differs from
   that of a conventional routing element, those models are, at least

   Perhaps the "third party architecture," or some such.
