Suresh,
[No hats on]
Hi Folks,
I have submitted a draft requesting a standard format for IPv6
extension headers. I would appreciate any comments on it.
I really like reading clear and concise drafts!!! Thanks!
While I agree that the problem that your draft is addressing is real,
I think in practice your proposal won't have very much effect on
fixing the problem. This will address new IPv6 extention headers
defined in the future, but it won't address other new protocols that
are defined that might show up after an IPv6 header, nor will it
address the ones that have been defined in the past. The result is
that a node that wants to parse all of the headers will still have to
still know about each one. It will even have to know that it is a
new IPv6 extension header that has this format. There is no bit or
flag that identifies an IPv6 extension header.
Also, for devices like firewalls the security implications of
skipping unknown (except for their format) headers isn't very good.
Finally, I think it is too late to be redefining the fragmentation
header.
Bob
p.s. I hope this draft doesn't mean that someone is thinking of
defining a lot of new IPv6 extension headers.... :-)
Thanks
Suresh

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
Title : Format for IPv6 extension headers
Author(s) : S. Krishnan
Filename : draft-krishnan-ipv6-exthdr-00.txt
Pages : 8
Date : 2006-10-18
In IPv6,optional internet-layer information is encoded in separate
headers that may be placed between the IPv6 header and the
transport
layer header. There are a small number of such extension headers
currently defined. This document defines a format for defining new
IPv6 extension headers.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
