Last Call Review of draft-ietf-ccamp-flexigrid-lambda-label-04

Hi!

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.

This document is on the Standards Track, and defines a new GMPLS lambda label
format in support of Flexi-Grid.

This document is very well written, comprehensive, and complete — thank you! In
particular, thank you for adding the Manageability Considerations section!

Summary: Ready with questions.

Major:

None.

Minor:

This document says it updates RFC 3471 and RFC 6205. It is not totally clear to
me how it is updating those RFCs. In general, defining a new feature or format
(e.g., new label encoding) creates a Normative dependency, not an Updates. In
particular, when a document updates another one, I believe that a Section
should be added explaining exactly what is updated (ideally with OLD/NEW text
format). Even less so I see the update to RFC 3471 by this document.

Could the exact details of what is updated be explained, and explicitly added
to the doc.

Nits:

Section 1: s/Packet Switching Capable (PSC)/Packet Switch Capable (PSC)/
(according to RFC 3471)

Hope these help,

— Carlos.
