There you go. I omitted logins, licensing and crypto, that's about it though.
I'm not too sure if I'm very knowledgeable on the DHCPv6 server on the Cisco. I'm not using it. I'm just using the DHCP client with prefix delegation and letting autoconfig do the rest.
With that in mind, if you are able to tell the DHCPv6 server to define the prefix that's provided by the DHCPv6 client, you should be able to use it. That's complete untested theory on my part though. I'll let someone else smarter than me comment on that :)

Also, this may be useful. (Xs) are just omitted potions of an IP. FE4 is my WAN plugged into my cable modem.
