Hi John,
I use v6 hosts routes on FreeBSD 4.11. The main purpose for me is through ipv6
in ipv6 tunnels, so it is different.
I tried to install host routes as you do:
In your case rtr2 and rtrg seem to be on the same prefix. In this case the
prefix route is enough, but if you want to add a host route, indeed the route
command does not work:
If i do not add a host route, but use the prefix route, the machine sending
traffic (rtrg) will make a neighbor sollicitation, then get a neighbor adv, and
add the entry in the routing table with the correct interface and the correct
gateway MAC address (rtr2 MAC address).
If i add a host route, I have the same entry excepty that the gateway MAC
address is my MAC address (rtrg)
To solve that, I do not add a route with route, but: add the v6 address of the
destination in /etc/hosts,
then:
ndp -s <hostname> <MAC address of the host>. Then the route is correctly added
to the routing table.
I hope it works for you and you have the MAC address of the destination but
still I find the behavior of the route command in this case strange.
Best regards,
Julien

Objet : Re: ipv6 host routes
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

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.
John
