SLAAC IPv6 only interface

[Roberto <mrgreiner@gmail.com>]

Hi,

I'm trying (as a lab exercise) to set an interface to activate only with 
SLAAC IPv6 address. No IPv4, no static, no dhcp. Problem is I can't find 
a configuration that makes the interface to startup without static or 
dynamic (dhcp) configurations.

What I've tried is something like

auto lo eth0
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet6 dhcp

instead of dhcp, I´ve tried dhcp6, dhcpv6, slaac, but to no avail. Does 
somebody know how to make this work?

I know the network is working. If I force the interface up with 
'ifconfig eth0 up', the interface does start, and it gets the IPv6 
address via slaac after a couple of seconds. But I can't find out what 
to put in the interfaces file to make it start automatically, without 
having any IPv4 address.

Any ideas?

Tks,

Roberto
