Re: [Int-area] Fwd: New Version Notification for draft-herbert-ipv4-eh-03.txt

["Templin (US), Fred L" <[e-mail]>]

Tom, if an IPv4 packet includes extension headers per this document, what happens if
the IPv4 header gets translated into an IPv6 header by some middlebox on the path?
Will the extension headers also require some form or translation, or will they happily
coexist with the new IPv6 header?

Thanks - Fred
