I have a question about
http://tools.ietf.org/html/draft-smyslov-ipsecme-ikev2-fragmentation-00#section-2.5.1
It states:
2.5.1. Fragment size
What is "message size" here referring to? The fragmentation payload, or
the total packet length?
That is, is it recommended that the packet size is 576/1280 including
the full IP header and ISAKMP header, or that the packet size is
576/1280 plus the IP header and ISAKMP header?
The total IP packet length (including IP header, UDP header, IKE header).
(and can the text in the next draft be clarified to indicate this
better?)
Sorry for being not very precise. I'll try to clarify it in the next version.
It might be more useful to implementors to know the IKE message size
upon which they should fragment, as opopsed to having to calculate the
values of IP headers, UDP headers and IKE header with fragmentation
payload themselves? So can the draft specify those (and or both) ?
