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.=20=20=20
