Mobile IPv4 Extension for Configuration Options Exchange
draft-ietf-mip4-gen-ext-04

According the WG chair Henrik Levkowetz, this document should go back to the WG for re-evaluation of the issue wrt DHCP or other means for communicating these configurations.

Verified that a note about 2nd WGLC had been sent to MIP4, but I could not find anything from the DHC list. Sent a reminder to the chairs.

Jabbered Henrik, and he agrees that 2nd WGLC is needed, after I explained that this is the procedure that we follow. In this case it may be even more important, given that this is not a simple option but a new transport.

Process message sent to DHC and MIP4 chairs:

Draft-ietf-mip4-gen-ext specifies a facility for a mobile
node to learn about configuration information in
the home network. What it does is in fact carry DHCP
options from the home network.

Pete, who is the document shepherd, feels that this
needs review from DHC WG and I fully agree (and
it would have been better if I had caught this
earlier, but I didn't -- sorry).

I would like to have either 2nd WGLC that extends to
the DHC WG as well, or alternatively, a quick review
by the Ralph and Stig followed by more review during
IETF LC. Ralph, Stig, can you take a look at the document
and recommend which approach we should use in this
case. (If the document seems reasonable from your
point of view then we might go to IETF LC.)

Pete McCann is the document shepherd. Yes, I have personally
reviewed the document and it is ready for publication.

The document has been adequately reviewed. I have no concern about
the reviews.

To be safe, the document should probably be reviewed by the dhc working
group during IETF Last Call to make sure there are no inconsistencies
with the way DHCP works and this draft.

No issues.

There is unanimous consensus to advance the document. I believe that
the WG as a whole understands the approach and is comfortable with the
document.

No appeals have been threatened.

No nits found by the automated checker, and no nits found during
manual proof-reading.

The document has 4 normative reference, each one a published RFC
of Proposed Standard or better status.

The IANA Considerations section is complete. One assignment from
the Mobile IP extension space for skippable extensions is requested.
Two new number spaces are created and both give a policy of approval
by Designated Expert. We have not yet discussed the appointment
of such an expert but will do so shortly.

No such formal notation is used.

> Technical Summary

Existing Mobile IPv4 specifications allow for the configuration of
a home address during Mobile IP Registration processing. This document
extends the range of parameters that can be configured during
registration
by allowing for the transport of arbitrary DHCP options in a Mobile IP
Registration Request or Response. The options are carried in a new
extension to the Mobile IP registration and borrow their structure from
existing DHCP options.

> Working Group Summary

The document completed last call in the mip4 working group in November,
2006.

Pete McCann is the document shepherd. Jari Arkko is the responsible AD.
