Shepherd writeup

(1) What type of RFC is being requested (BCP, Proposed Standard,
Internet Standard, Informational, Experimental, or Historic)? Why is
this the proper type of RFC? Is this type of RFC indicated in the
title page header?

This I-D is being progressed for publication as a Proposed Standard.
The I-D proposes new extensions which will need IANA action and hence
the standards track is appropriate.
The type of RFC is indicated in the title header of the I-D.

(2) The IESG approval announcement includes a Document Announcement

Technical Summary:

   Access Network Identifier (ANI) Mobility option was introduced in
   Access Network Identifier Option for Proxy Mobile IPv6 (RFC 6757).
   This enables a Mobility Access Gateway (MAG) to convey identifiers
   like network identifier, geolocation, and operator identifier.  This
   specification extends the Access Network Identifier mobility option
   with sub options to carry civic location and MAG group Identifier.
   This specification also defines an ANI Update-Timer sub option that
   determines when and how often the ANI option will be updated.

Working Group Summary:

The WG initially considered updating RFC 6757 (Access Network
Identifier (ANI) Option for Proxy Mobile IPv6). However after
considering the scope and the extensions being proposed, it was
decided that a separate I-D extending RFC 6757 was a better approach.
Consensus was strong to create a new WG I-D and extend RFC6757.

Document Quality:

Are there existing implementations of the protocol?

  Not at the present time.

Have a significant number of vendors indicated their plan to implement
the specification?

  At least one vendor has expressed plans to implement this

Are there any reviewers that merit special mention as having done a
thorough review, e.g., one that resulted in important changes or a
conclusion that the document had no substantive issues?

  All reviewers have been acknowledged in the I-D.

If there was a MIB Doctor, Media Type or other expert review, what was
its course (briefly)? In the case of a Media Type review, on what date
was the request posted?

  The document does not specific a MIB or media type.

(11) Identify any ID nits the Document Shepherd has found in this
document. (See and the

(13) Have all references within this document been identified as
either normative or informative?


(14) Are there normative references to documents that are not ready
for advancement or are otherwise in an unclear state?

   All normative references are published RFCs.

If such normative references exist, what is the plan for their


(15) Are there downward normative references references (see RFC
3967)? If so, list these downward references to support the Area
Director in the Last Call procedure.


(16) Will publication of this document change the status of any

Are those RFCs listed on the title page header, listed
in the abstract, and discussed in the introduction?

   Yes. Listed in the abstract.

clearly identified. Confirm that newly created IANA registries include
a detailed specification of the initial contents for the registry,
that allocations procedures for future registrations are defined, and
a reasonable name for the new registry has been suggested (see RFC
