Apparently, I've done a stupid thing and forgot my Ubuntu Server in AWS
is Server 14. I've upgraded the ubuntu to 16.04 a few months back, but
forgot that it's supposed to be still Ubuntu Server 14.
So I followed the guide https://docs.aws.amazon.com/vpc/latest/userguide

So, nobody will look into this anymore (apparently), are we moving to
systemd's networkd (16.04) to "fix" this? I'm so tired of ifupdown...

This is still broken on latest ubuntu server 14.04. No wonder that ipv6
gets no adoption when one needs hours (or dig through bug reports) to
get a basic ipv4/ipv6 dual stack setup working.

BTW, Debian testing also suffer from this problem.
I'm seeing 3 main problems (Ubuntu / Debian with IPv6):
1- ifupdown doesn't have support for:

* conectivity only starts after "ping6 gateway_ip";
* impossible to manage "IPv6 Aliases", since there is no need
This bug is still not fixed in Ubuntu 14.04.
It is VERY annoying.

An easy fix here will be to use following tweak
iface wlan0 inet dhcp
iface wlan0 inet6 dhcp
accept_ra 1
autoconf 1
pre-down wpa_cli -i$IFACE reconnect 2>/dev/null
this way it will try pre-down before starting down action. Pre-down
eventually fails since wpa is already dead.

I'd like to request a backport of this for 12.04 LTS as well, this issue
has forced me to move to NetworkManager on my server instead of
ifupdown, as DHCPv6 stateful support is seriously broken unless I
manually add default routes.

P.S.: I just found a possible workaround for the fact that configuring
accept_ra does not work. In addition to the above one, up sysctl
net.ipv6.conf.$IFACE.accept_ra=1, you can install the ndisc6 package and
add up /bin/rdisc6 $IFACE to cause a manual discovery from userspace.
However I'm not sure

I stumbled over this as well. Fortunately we use Ubuntu 12.10, so I
could use the "accept_ra 1" workaround to fix the issue (missing default
routes when using stateful DHCPv6 to obtain address).
