Hi Jiabo,
Thanks for your reply, I didn't figure out why FreeBSD 7.1 doesn't
recover from the DAD, but I had a work around on this which is to run
the test manually with out the vel tool and reboot the FreeBSD box
between the first and the second half of test 1.2.B.
However, I have another problem while running the NetBSD box as
target-host, which is, the NetBSD box does not send out Neighbor
Solicitations when the interface comes up, I saw you asked about this on
the web, I don't know if you have found out a solution yet, could you
give me some suggestions on this issue?
Thanks,
Bin
