Re: IPv6 Subscriber Access Deployments

If you use separate VLANs for each customer then the CPE router doesn't even require an external IPV6 address for DHCPv6-PD. IPV6 link-local addresses can be used between your BRAS and customer CPE router. Some CPEs can even allocate a WAN/mgmt IPV6 address out of the delegated subnet via DHCPv6-PD.

Short answer to that is “DHCPv6-PD”

Once the router has an external address communicating point to point with the ISP router, it should then send an DHCPv6-PD request asking for a prefix that it can manage. The ISPs DHCP server should then send back a /48 (or if you want to be silly, a /56 or a /60, and if you want to be insane, a /64).
