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.

Intended Status: Informational

Summary: 

No issues found. This document is ready for publication.

Comments:

This document provides an information model for the Babel protocol. It uses
a pseudo programming language like notation to enumerate a lisdt of objects
that collectively comprise the information model. It appears that the
primary purpose of this document is as a reference source for implementors
of this protocol.

This is not an easily readable document, but I believe that was never the
intention. This is a list of objects and the hierarchical structure in which
the objects are placed.

The document does not attempt to justify why these objects are listed here,
nor does it elaborate as to their intended role other than a brief
functional desription of the information that is denoted by the object.

Major Issues:

None

Minor Issues:

None

Nits:

It seems anomalous to this reviewer that it goes to the bit lengths of some
integer valued objects, yet leaves string objects undefined in terms of any
maximum length. 

"centiseconds"? Really? "tenths of seconds" would be clearer to most
readers!
