I have a problem with my default IPv6 route not coming up after boot on a Debian Squeeze system. This is my config (/etc/network/interfaces):
# Loopback device: auto lo iface lo inet loopback iface lo inet6 loopback # device: br0 auto br0 iface br0 inet static bridge_ports eth0 bridge_fd 0 address 88.198.62.xx broadcast 126.96.36.199 netmask 255.255.255.224 gateway 188.8.131.52 up route add -net 184.108.40.206 netmask 255.255.255.224 gw 220.127.116.11 br0 iface br0 inet6 static address 2a01:4f8:131:10x::2 netmask 64 gateway 2a01:4f8:131:100::1 up route -A inet6 add 2a01:4f8:131:100::1/59 dev br0
My inet comes up alright, but I have to exec the route command manually after boot to make IPv6 work. Otherwise I can't even reach my gateway.
This is the output of ip -6 route show after boot:
2a01:4f8:131:10x::/64 dev br0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 unreachable fe80::/64 dev lo proto kernel metric 256 error -101 mtu 16436 advmss 16376 hoplimit 4294967295 fe80::/64 dev br0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295
I already tried it with:
up ip -6 route add 2a01:4f8:131:100::1 dev br0 up ip -6 route add default via 2a01:4f8:131:100::1 dev br0
in /etc/network/interfaces, but with the same results. If I execute those commands manually on my shell, everything starts working nicely. And yes, I tried with post-up instead of up, too.
Only other changes I made was to activate ip forwarding for IPv6, because I want to run some LXC containers on that system.
