Setting up the subnet on linux 2.6

Salutations,
I used to have an xs4all ipv6 tunnel, however because I ended my subscription, I was forced to remove that as well. Finally the time for me to try a SixXS subnet has arrived. 8-)
I am using aiccu to setup my 'primary link' (is that the right term?) and I can ping6 to ipv6 hosts. My server has eth0 as internet (not behind NAT / router), and eth1, eth2 and eth3 for LAN segments. I haven't setup the subnet yet.
My question is; is it enough to bind subnet addresses to eth1, eth2 and eth3 then and activate the subnet? Or is further action required? I am using radvd to delegate /64 subnets and i understand how to set that up. However, I'm not getting started on delegating the subnet until I understand the appropriate action.
Thanks for the help,
Mark.

I figured, "might as well try it out and see how far I could come," and voila, got it working in no time. (I should be more confident next time |:( anyway, here are some tips for new IPv6 explorers on how I got it to work.)
I use aiccu to setup my primary IPv6 link to SixXS. This creates a 'sixxs' ip interface with one IPv6 address.
Anyway, what I did after I received my subnet details is this: If my tunnel would be 2001:838:efg::/48 (which ofcourse it isn't), I gave eth1, eth2 and eth3 the addresses 2001:838:efg:1::1/64, 2001:838:efg:2::1/64; and 2001:838:efg:3::/64. Then I configured radvd:
interface eth1 {
AdvSendAdvert on;
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
AdvDefaultPreference high;
AdvHomeAgentFlag off;
prefix 2001:838:efg:1::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
};
interface eth2 {
AdvSendAdvert on;
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
AdvDefaultPreference high;
AdvHomeAgentFlag off;
IgnoreIfMissing off;
prefix 2001:838:efg:2::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
};
interface eth3 {
AdvSendAdvert on;
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
AdvDefaultPreference high;
AdvHomeAgentFlag off;
prefix 2001:838:efg:3::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
};
This was enough to make it work. Ofcourse client PC's usually don't need more configuration than enabling IPv6. Good luck to anyone having troubles 8-)

Hmm, well, I have added this and it's been working for a while now. Without problems; however, for some reason my WindowsXP clients get allocated two IPv6 IP's instead of one! And only one is a valid EUI-64 address (i think.)
Could anyone please help me with this? I don't want two allocated IP's per connection, only one. The linux clients have no problems with this...
