Hi,

your "ip addr show eth0.1" output shows, that you don't have a ipv6 link local adress, so my guess is that you haven't load the ipv6 module at all. Without a link local adress (which is comfigured automaticly, regardless of your network connection) router announcements/solicitation can't work at all.

If you load the module and have "proc/sys/net/ipv6/conf/all/accept_ra" and "proc/sys/net/ipv6/conf/all/autoconf" enabled (that's the default on linux hosts), then your box will get a IP automaticly via router announcements (accept_ra).

If you enable "proc/sys/net/ipv6/conf/all/forwarding" then the default is not to accept dynamic ipv6 ips from other routers.

hope this help you a bit... but you are right, documentation is missing.

i had to create a file in the /etc/modules.d/ directory to get the ipv6 module loaded everytime. Maybe we should add this in the packages.

Hi Thorsten,

::1/128 on your loopback device shows that ipv6 is loaded, sure, but there must be something wrong in your setup or in even in the trunk-code. because each interface should have an link local adress. this should look like this:

inet6 fe80::217:11ff:feaa:9033/64 scope link

if you don't have a fe80 link local adress on your interface, then communication via ipv6 cannot work and that's why you got problems with the router annoncements. But I don't have a clue why you don't have these link local adress.

What is your exact plantform? recent trunk version on asus router? We should try to reconstruct this. broken ipv6 in trunk would be quite bad and needs to get fixed for 1.1.
