Ok, I still have no joy adding an IPv6 route. Can anybody tell me what I
do wrong?

What I understand from the route(8) man page is that this command should
work:

route add -inet6 rtr2 rtrg -interface

Where rtr2 is the destination address and rtrg is my address on the
interface that rtr2 is connected to.

I have the following lines in my /etc/hosts file:
2001:4200:7000:15:202:6fff:fe22:9547    rtrg
2001:4200:7000:15:202:6fff:fe41:1927    rtr2

When I do the route add command the kernel prints this message:

nd6_rtrequest: bad gateway value: ath0

Ifconfig of the interface looks ok to me: 
ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet6 fe80::202:6fff:fe22:9547%ath0 prefixlen 64 scopeid 0x3
        inet6 2001:4200:7000:15:202:6fff:fe22:9547 prefixlen 64
        inet6 2001:4200:7000:15:: prefixlen 64 anycast
        ether 00:02:6f:22:95:47
        media: IEEE 802.11 Wireless Ethernet autoselect <adhoc> (autoselect <adhoc>)

        authmode OPEN privacy OFF txpowmax 24 bmiss 7 burst bintval 100

After the route add, this new entry arrived in the routing table according
to:
netstat -rnf inet6
2001:4200:7000:15:202:6fff:fe41:1927 2001:4200:7000:15:202:6fff:fe22:9547 UHS
     ath0

I looked with ndp -a, but nothing was added there.

Anybody got any ideas? This is the last part of getting olsrd to work
properly on FreeBSD using IPv6.
