I did some research into this to v6-ify an ISP earlier in the year and YMMV depending on IOS with the actual behaviour of your routers compared to this document. This is another supporting case for starting the implementation yourself as early as possible because if you were planning on following the guides, you may find yourself spending a LOT of time manually testing which parts of the doc don't follow the behaviour of your gear.<div>

</div>Cisco have done a pretty good job of documenting it here:<br>
<a href="http://www.cisco.com/en/US/docs/ios-xml/ios/ipv6/configuration/xe-2/ip6-adsl-dial.pdf" target="_blank">http://www.cisco.com/en/US/docs/ios-xml/ios/ipv6/configuration/xe-2/ip6-adsl-dial.pdf</a><br>
<br>
The usual practice would be to have an ipv6 local pool on the<br>
LNS which is used to assign a prefix for SLAAC-derived interface IDs,<br>
then for the CPE to request a delegated prefix by DHCPv6. The LNS<br>
will answer the DHCPv6 query using data returned by Radius.<br>
<br>
You probably want to use a Framed-IPv6-Prefix or the<br>
ipv6:delegated-prefix Cisco-AVPair instead of a Framed-IPv6-Route,<br>
for what it's worth.<br>
<br>
A far wordier, more detailed guide for IOS is here:<br>
<a href="http://www.cisco.com/en/US/docs/ios-xml/ios/ipv6/configuration/xe-2/ip6-adsl-dial.pdf" target="_blank">http://www.cisco.com/en/US/docs/ios-xml/ios/ipv6/configuration/xe-2/ip6-adsl-dial.pdf</a><br>
<br>
The documentation available is substantially better than it was<br>
at this stage last year.<br>
