Hi all,

While going through the draft I've come up with a load of questions and
notes. Addressing these will make the draft more complete and resolve some of
the ambiguity which might affect an implementation.

I'm going to divide these into a number of emails so that it should be easier
to follow each discussion.

This email is about Sequence numbers (Section 6.4 in Version 9a or Section
4.4 in Version 9b):
The draft says we can use multiple SeqNums ("one per IP address"). What if
there are multiple IP addresses on each interface - should they have a SeqNum
each, or share one SeqNum? Should it be one SeqNum per interface? Or since we
associate the SeqNum with a route to a Router Client, should it be one SeqNum
per Router Client?
If using multiple SeqNums, should we store the sequence number in the
interfaces list? (I have said we could do this in the draft)
When sending a RREQ on multiple interfaces, would the sequence number be the
same in all of them?
When sending retries for a RREQ, is the SeqNum updated?
Is TargSeqNum ever used in the RREQ? Is it something to do with iRREP? If so
should we have references to it in the main text?
Henning and I were wondering the same thing... We couldn't figure out where
TargSeqNum was actually used. Do we still need this feature?

Regards,
Lotte

Comments welcome :-)

Kind regards,
Vicky.
