Hello,
I'll try to make it as brief as possible.
I have a Freebsd 4.0 connected through a v6-on-v4 tunnel to a remote
router. The gif0 tunnel works fine (can ping the other v6 end).
My local v6 address is 3ffe:8038:80:3::3, configured on the fxp1 (ethernet)
interface, the other end is 3ffe:8038:80:3::2 .
There is no autoconfiguration so I edited /etc/rc.conf so that
/etc/rc.network6 adds the local address it gets from there.
When I originally booted the station, netstat -rn output was:
3ffe:8038:80:3::/64 link#2 UGSc fxp1
What adds this line? could not find it in rc.network6
My second question is: what link#2 stands for?
I could not ping the other v6 end with that, so I added manually a route:
3ffe:8038:80:3::2 gif0 UHS gif0
and I would get ping6 replies.
Still, I could not seem to get replies from further hops, which are within
3ffe:8038:80:3::/64 too. So I deleted the first entry to
3ffe:8038:80:3::/64 and added another one, so my routing table now looks
like this:
3ffe:8038:80:3::/64 3ffe:8038:80:3::2 UGSc fxp1
3ffe:8038:80:3::2 gif0 UHS gif0
3ffe:8038:80:3::3 0:d0:b7:20:8a:7b UHLW lo0
But, when I try to ping6 further down some hops (3ffe:8038:80:3::1 for
instance), now I get messages:
/kernel: nd6_lookup: failed to add route for a neighbor
(3ffe:8038:0080:0003::0002)
Any idea what this message means/where it comes from/what I am doing wrong?
I know I should use route6d instead of struggling with static routes (and I
will) but I need to satisfy my curiosity first.
DH.
