Hi Mark,
Thanks for the clarification.
When I looked at the looping issues in sec11. It is a little hard for me to
understand how such attack launched. I can hardly find looping related
discussions between the last 2 meetings in the mailist. I downloaded
your presentation, but the attack illustration pages are broken (I am not
sure it is because the original one online was broken or my pdf software
has a compatibility problem). Could you send me a copy?
Specifically, it is not clear about the sentence2, para3, sec11
If the attacker constructs the
packet
accordingly, and can inject a packet with an IPv6 source address that
looks as if it originates from within the 6rd domain of the second
^^^^^^^^^^^^^^^^^^
border relay, [...]
^^^^^^^
Did you mean the 6rd domain the second border relay is serving? Does
the second border relay serve the same domain as the first BR? (since
a domain allows for multiple BRs, IMO)
BTW, is it OK to define 6rd domain in sec3? I saw this term everywhere.
Or you think the definition is too obvious to be explicitly stated?
Thanks,
washam
