Hi
Francis/Jhon
Thanks for your information. Why IPv6 Broadband access service is so
dependent on DHCP6. Even if you run DHCP6-Relay on NAS there is some
problem in NAS for maintaining Route-information, Since NAS does not
know
What prefixes are allocated to internal access networks. Since CPE
Device
Again needs to inform routing information to NAS, CPE device may not
support routing protocols like BGP, OSPF.
There should be a simple prefix delegation mechanism such that NAS can
directly use to advertise prefixes from AAA to its Access clients
without using DHCP6 server. If you don't support DHCP6 then IPv6 AAA
does not have much use in NAS.

I agree with Francis on this.
