Hi list,
i have a difficult time reaching my default IPv6 default gateway in a
different subnet. Asking Google brought up some threads from early 2011.
Most of the solutions where switching the prefixlen to reach the gateway
but this didn't work out for me. The mentioned route commands didn't
work out for me, too. The support said, as they don't provide OpenBSD on
their machines, they don't support it. They told me, to set up one IP
from my network and add a host route to the gateway.
My network is 2001:4ba0:ffff:00ab::0 /64
The gateway is 2001:4ba0:ffff:1:beef::1
The provided example for FreeBSD (not verfied):
route add -inet6 [ipv6-gateway] -iface [interface]
ndp -s [ipv6-gateway] [mac-gateway]
route add -inet6 default [ipv6-gateway]
The provided example for Linux (verfied with provided rescue console):
~ # ip -6 route add 2001:4ba0:ffff:1:beef::1 dev eth0
~ # ip -6 route add default via 2001:4ba0:ffff:1:beef::1
~ # ip -6 route show
2001:4ba0:ffff:1:beef::1 dev eth0 metric 1024
2001:4ba0:ffff:ab::/64 dev eth0 proto kernel metric 256
fe80::/64 dev eth0 proto kernel metric 256
default via 2001:4ba0:ffff:1:beef::1 dev eth0 metric 1024
~ # ping6 ipv6.google.com
PING ipv6.google.com(la-in-x6a.1e100.net) 56 data bytes

That's what i did on OpenBSD:

Pinging any ipv6 host is gives me "No route to host":
~ # ping6 ipv6.google.com

I can't even reach the gateway:
~ # ping6 2001:4ba0:ffff:1:beef::1
PING6(56=40+8+8 bytes) 2001:4ba0:ffff:ab::1 --> 2001:4ba0:ffff:1:beef::1

round-trip min/avg/max/std-dev = 0.031/0.041/0.052/0.011 ms
Trying to set the route just as default isn't working:
~ # route add -inet6 default 2001:4ba0:ffff:1:beef::1
route: writing to routing socket: Network is unreachable
add net default: gateway 2001:4ba0:ffff:1:beef::1: Network is unreachable
Anyone has any idea how i can reach the gateway?
Cheers,
Marc
