Hi Ole There is no ND at all, that is, no NA/NS/RA/RS etc. You can check the document Sheng sent out in previous emails. In WiMAX, DHCPv6 is mandatory while ND is optional. In a word, in some scenarios, DHCPv6 is the only way to configure IP address.
By the way, operators are more familiar to DHCP than ND, and they get used to DHCP for address management. You are right that we should avoid duplicate mechanisms for the SAME scenario. However, this is different.

"when there is no SLAAC" does that mean? - there is no RA - there is an empty RA (no PIO) - the PIO has A-flag off if I understand your draft correctly, you want a DHCPv6 alternative to the RA PIO option. generally we try to avoid duplicate mechanisms, so could you please give a use case? cheers, Ole -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
