When I issued the following command by accident today:
=20
route add default -inet6 fe80:20d:56ff:fe8d:d4b0%fxp0
The netstat shows the following:
Internet:
Destination Gateway Flags Refs Use Netif
Expire
default fe80:20d:56ff:fe8d:d4b0%fxp0 UGS 0
0 fxp0
10.9.44/24 link#1 U 1 0 fxp0
10.9.44.175 127.0.0.1 UGHS 0 0 lo0
127.0.0.1 link#4 UH 1 4 lo0
So I went ahead and issued
route add 10.1.1.1 -inet6 fe80::1%fxp0=20
Internet:
Destination Gateway Flags Refs Use Netif
Expire
default fe80:20d:56ff:fe8d:d4b0%fxp0 UGS 0
0 fxp0
10.1.1.1 fe80::1%fxp0 UGHS 0 0 fxp0
10.9.44/24 link#1 U 1 0 fxp0
10.9.44.175 127.0.0.1 UGHS 0 0 lo0
127.0.0.1 link#4 UH 1 4 lo0
I verified this behavior on both FreeBSD 5.4 Release and 6.0-CURRENT.
I think this behavior is probably not intended and should be treated
as a bug. I did a quick patch in sys/net/route.c
(it's just as easy in sbin/route.c).

After the patch,

heavygear# route add 10.1.1.1 -inet6 fe80::1%fxp0
route: writing to routing socket: Operation not permitted
