[Bug 1021398] Re: ifup bridge devices does not work with inet6

[Stéphane Graber]

ifupdown works sequentially, so in this case you're asking it to
configure an ipv6 address on an interface you haven't defined yet.

Move the "iface br0 inet6 auto" after the "iface br0 inet static"
section, that should fix it.

Also, I don't think you actually need that line at all as the kernel's
default behaviour is to accept router advertisement.

Marking the bug invalid as that syntax is indeed invalid. Fell free to
move it back to new if the bug still happens after fixing the ordering.

Title:
  ifup bridge devices does not work with inet6

Status in “ifupdown” package in Ubuntu:
  Invalid

Bug description:
  using a bridge device configured like this:

  auto br0
  iface br0 inet6 auto
  iface br0 inet static
          address 10.8.10.192
          netmask 255.255.254.0
          gateway 10.8.10.1
          dns-nameservers 10.1.1.11 10.1.0.11
          bridge_ports eth0
          bridge_stp off
          bridge_fd 0
          bridge_maxwait 0

  auto eth0
  iface eth0 inet manual

  
  yields an error when bringing up with ifup

  error: "net.ipv6.conf.br0.accept_ra" is an unknown key
  Failed to bring up br0.

  
  commenting the inet6 line solves the problem.
