[6bone] Router solicitation strangeness?

[John Klos]

Hello,

I was wondering if anyone might have any helpful clues for me. I'm trying
to figure out why a simple NetBSD 1.6.2 host doesn't get an IP from a
router solicitation. Other NetBSD hosts on the same network do, and so do
Mac OS X machines, but something's not right.

The IPv6 router is also running NetBSD 1.6.2 (rc1), and the only strange
thing I can think of is that the MAC address of the ethernet card in the
machine which doesn't work is a little different than most
(ae:55:53:00:11:d9).

I'm also having an issue with creating a working rtadvd.conf for subnets,
but that's another story - perhaps someone can help me with that offline.

I did a tcpdump, which is shown below; does anyone have any suggestions on
what else I should try or do?

Thanks,

Here is a Mac OS X machine doing a successful router solicitation:

And here is what I see when the Amiga tries to do a router solicitation:
