As is customary, I have done my AD review of
draft-ietf-ospf-node-admin-tag-04
before requesting IETF Last Call.

First, I'd like to thank the working group and Shraddha, Harish, Hannes,
Rob,
Anton, Zhenbin, and Bruno for their hard work on the draft.  However, this
short
draft has 7 authors, which is a couple over the author limit for RFCs.
Experience
has shown that it takes much longer to process a draft through AUTH48 and
the
other steps necessary (responsiveness to comments, agreement, etc) with a
large
number of authors.  While I am willing to be persuaded - on or off list -
that all 7
of the current authors are actively editing, I would prefer that a smaller
number be
selected as the active editors.

While that discussion is ongoing, here are my technical comments.  In
general,
the draft is in good shape but could use some English grammar editing; I
have not
tried to indicate all the places where "the" is missing, for instance.

1) In the abstract: "This optional operational capability allows to
   express and act upon locally-defined network policy which considers
   node properties conveyed by tags."

   What is the subject that "to express and act upon"?  Is it a router?
   Please clean up.

2) In Sec 3.2: "The TLV SHOULD be considered an unordered list."  Perhaps
   "the value contents of the TLV" or something that makes it clearer?

3) In Sec 4.3: " [RFC7490] proposed method of"  should be
   "[RFC7490] defines a method of"

4) In Sec 5, I'm fairly certain that admin tags can leak additional
   information to an IGP snooper.  It would be useful to have some thoughts
   about that.

5) In IANA considerations, please duplicated the suggested value (10) that
   was mentioned in Sec 3.1

Thanks again for the hard work.  The sooner we resolve whom the editors are,
the sooner this draft can proceed.  Ideally, if updated by Thursday, it
could enter
IETF Last Call and make the IESG telechat on Oct 17.

Regards,
Alia
