I was trying to follow the post here: http://www.tunnelbroker.net/forums/index.php?topic=224.0 that was very helpful but I don't think I quite have it. My clients (Vista, Debian) don't seem to be auto configuring themselves since they still have still have link-local addresses?
Tunnel connection.

Hi,
You need to advertise your subnet using neighbour discovery:
ipv6 nd prefix 2001:470:XXXX::/64 infinite infinite
the two last commands define how long the IPv6 addresses 'last'
Note that you won't get DNS servers advertised to clients this way. That requires DHCPv6 which unfortunately isn't well supported yet...
What routing platform are you on? I've got a 2621xm and my router issued RAs by default. My ASA5505 does the same thing.

I applied
ipv6 nd prefix 2001:470:xxxx:xxx::/64 infinite infinite
to the internal interface f0/1.2 but my client didn't seem to pickup the IP from the router? Which ipv6 IP should I be using?
Here's what my internal interface looks like.
#sh ipv6 int f0/1.2

I didn't have #ipv6 unicast-routing
I've been told three different methods and since I'm also new to this I'm just trying to figure out the benefits to each one. Basically I'm asking why bother with the latter two if the first one works?
ipv6 address 2001:470:880D::1/64
ipv6 nd prefix 2001:470:1F07:3B6::/64 infinite infinite
