Package: ifupdown
Version: 0.7.47.1
Severity: important
Tags: ipv6

ifupdown with "inet6 dhcp" in /etc/network/interfaces breaks stateless
IPv6-conifg.

/etc/network/interfaces:
auto eth0
iface eth0 inet6 dhcp

auto configures eth0 with a ipv6-address but the networkdevice gets no gateway
from the radvd.

After that I bring the networkdevice down with "ifdown eth0" and then manual
with
ip link set dev eth0 up
or
ifconfig eth0 up
but the networkdevice don't get a gateway and or an ipv6-address (if radvd
advertise a addressprefix)

I have to reboot to solve the problem!

If I disable "iface eth0 inet6 dhcp" in /etc/network/interfaces reboot and do
it by hand:

ip link set dev eth0 up
        now the networkdevice has a gateway!
dhclient -6 eth0

everything ist fine.
