Thoughts about RA en DHCPv6 in /etc/network/interfaces

Hi all,

On a test network I just installed a Debian server. On this network RA
are being sent for SLAAC, just for testing.

I configured a static IPv6 address in /etc/network/interfaces with the
line "iface eth0 inet6 static", all works good. However, because RA are
being send I also have a SLAAC address, resulting in two IPv6 addresses.
I know that I can disable the SLAAC behaviour somewhere in a config file
but that is not the point.
Wouldn't it be better if RA messages be ignored once you specified
"iface eth0 inet6 static"? This result in a more understandable
configuration and I also think a lot of administrator will neglect to
turn off RA configurations once the server has a static address,
resulting in a possible security/stability issues when RA are start
being sent by either a legitimate or rogue node.

It would then be nice if you can control the behaviour, just like IPv4,
in /etc/network/interfaces with something like "iface eth0 inet6 ra" and
"iface eth0 inet6 dhcpv6".

What do you think?

Kind Regards,
