IP6 subnet configuration

Hi,
Just need a little help setting up my IP6 subnet. The machines that matter are all running Linux.
I have a network with all machines connecting through a single router to the internet. One of these machines has AICCU installed, which gives IP6 connectivity.
I applied for a subnet but am unsure as to the correct configuration of radvd.
My tunnel information is
Subnet IPv6 : 2a01:348:2e5::/48
Routed to : 2a01:348:6:485::2/64
Do I use prefix = 2a01:348:2e5::/64 in radvd.conf?
Do I have to manually configure an IP6 address for the eth0 interface on that machine, if so what would be recommended?
Thanks in advance,
AndyR

Depending on kernel version it seems the generic answer is 'yes'.
Recommendations are the simple <prefix>::1 or cut & paste the EUI-64 portion of the link-local address into it (thus if you have:
# ifconfig
eth0 Link encap:Ethernet HWaddr 00:18:51:a8:96:58
inet addr:172.16.99.58 Bcast:172.16.99.255 Mask:255.255.255.0
inet6 addr: fe80::218:51ff:fea8:9658/64 Scope:Link
The link-local is fe80::218:51ff:fea8:9658 and the EUI-64 portion is :218:51ff:fea8:9658, as such in your case that would make: 2a01:348:2e5:218:51ff:fea8:9658 or for the simple one: 218:51ff:fea8:9658::1 ;)

Thanks for confirming that. I used the EUI-64 version, because then I can use another machine running radvd and the address won't change.
It all just seems to be working rather smoothly (slightly worrying).
Thanks.
