To cut a long story short, I have a virtualized environment (vbox ontop of
solaris11) with a couple of freebsd vms. The ipv6 address assignment keeps
failing due to duplicated addresses. From what I can see this is basically
due to multicast frames being looped back to the guest OS. In my simplistic
mind i should just disable dad and do it all manually. I cant find how to
do this though. I know this isnt a bsd thing as the linux guests have the
same issue.
