Reviewer: Fred Baker
Review Result: Ready

I have reviewed this document as part of the Operational directorate's
ongoing effort to review all IETF documents being processed by the IESG.  These
comments were written with the intent of improving the operational aspects of the
IETF drafts. Comments that are not addressed in last call may be included in AD reviews
during the IESG review.  Document editors and WG chairs should treat these comments
just like any other last call comments.

I read the draft in some detail. My big catch was, in section 5.4:

   Given the fact that SPF algorithms are based on the assumption that
   all routers in the routing domain calculate the precisely the same
   SPF tree and install the same set of routers

The assumption is that all such routers install the same set of *routes*, not *routers*.

And frankly, if that was my biggest issue, the draft is in pretty good shape.

The fact that there is a highway to hell and a stairway to heaven is an interesting comment on projected traffic volume...
