Shepherd writeup
draft-ietf-ipsecme-ikev2-fragmentation

1. Summary

Paul Hoffman (IPsecME WG co-chair) is the document shepherd and Kathleen Moriarty is the
responsible AD.

This document describes a method to avoid IP fragmentation in large IKEv2 messages. It shows
how to perform fragmentation in IKEv2 itself, replacing them by series of smaller messages.
This allows IKEv2 messages to traverse network devices that don't allow IP fragments to pass
through.

Given that this is a protocol extension, it is meant to be a Proposed Standard.


2. Review and Consensus

The WG discussion of the document was fairly good, with about average participation (which
for the IPsecME WG means "the chairs had to beg a bit for more participants, but we then got
them"). We also got a "TSVDIR-ish review" of the draft, which got good discussion on the
list. There was a reasonable amount of give-and-take, and the WG Last Call was uncontentious.
A significant point was brought up during IETF Last Call, and was added to the Security
Considerations.


3. Intellectual Property

The author has stated that their direct, personal knowledge of any IPR related to this
document has already been disclosed, in conformance with BCPs 78 and 79.


4. Other Points

There are no normative downrefs.

The IANA Considerations are short and to the point. The expert review for the two items
there has not been done yet, but the designated expert participated in the WG Last Call, so
this is not likely to be an issue.
