Julian wrongs here.
Try the patch please.
I've found the superfluous code in nd6.c when wrote a patch for
divert(4) and was very annoyed this loopback behaviour.
For unknown reasons KAME authors decided to fake interface for loopback.
It differs from IPv4 code, so, I guess, it should be fixed. But I could
not proof it. Your example is better for this.
