Bug Description

Binary package hint: ifupdown

This /etc/network/interfaces does not configure the static ipv6 address on bootup (only the link-local):

auto lo eth0
iface lo inet loopback
iface eth0 inet static
  address 130.239.18.226
  netmask 255.255.255.128
  broadcast 130.239.18.255
  gateway 130.239.18.129
iface eth0 inet6 static
  address 2001:6b0:e:2018::226
  netmask 64

But this one works:

auto lo eth0
iface lo inet loopback
iface eth0 inet6 static
  address 2001:6b0:e:2018::226
  netmask 64
iface eth0 inet static
  address 130.239.18.226
  netmask 255.255.255.128
  broadcast 130.239.18.255
  gateway 130.239.18.129

There is no mention of such a limitation in the manual for interfaces(5) and is rather confusing since there is no error mention, it just comes up without 2001:6b0:e:2018::226 for eth0.

I can comfirm this bug AND the given workaround.

Took me some weeks lacking usable IPv6-support to find this hint. :-(

i have a similar problem, only not even the link local address is configured for interfaces that already have an IPv4 address when the ipv6 module is loaded

I can confirm that this affects hardy, but it appears to be fixed on lucid.

I don't see this problem on maverick. I wonder what change caused the fix?
