IPv6 and static assignments for ADSL services

Hi,

I'm working through the deployment of IPv6 on our network.  We have some ADSL customers and therefore, I need to offer dual stacked - with the view to one day just offering IPv6.

I've managed to configure our LNS (Cisco 7204 G1) for IPv6 and have a Cisco 1841 connect to it and be assigned and IPv6 address from a pool. However, as most of our customers are businesses and will also require additional /64's for their LAN segments, then I need to be able to assign static IPv6 addresses via RADIUS.

The problem is that I don't seem to be able to get the virtual-template config right. 

Can anyone offer some suggestions about what changes may need to be made to my configs below?

interface Loopback1

description Loopback for customer DSL

ip address xxx.xxx.xxx..254 255.255.255.255

ipv6 address xxxx:xxxx:0:1::1:2/128

ipv6 enable

interface Virtual-Template2

description Authentication from DSL supplier

ip unnumbered Loopback1

ip flow ingress

ip tcp adjust-mss 1440

peer default ip address pool default

ipv6 unnumbered Loopback1

ipv6 enable

no ipv6 nd ra suppress

ppp mtu adaptive

ppp authentication chap radius

ppp authorization radius

Thanks,

Jonathan

I got it sorted - it was a radius related issue.
