Thank you for your clarification to the point. Actually, we proposed both RA and DHCP options for source address selection at first. But we came to think that DHCP is more appropriate for this purpose for the reasons you raised above. Also, DHCP-Lite is stateless as you know, so it seems to us that it is much easier to implement and to operate for almost all the cases we suppose. That is why we focus on DHCP option right now. -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
