RFC3633 / RFC6204. RFC3633 _is_ a protocol. I don't understand what you mean by "what protocols should support PD". > Let's say we have a router supporting 1 WAN and 1 LAN.

PD delegates a prefix to the LAN-side links, not the WAN side. for the WAN side normal address assignment is used (SLAAC, DHCP). > As I know, the router must request for another prefix (e.g. > 2001:1234:5678::/48) and assign a suitable prefix (e.g. > 2001:1234:5678:ABCD::/64) > to its LAN, by using Radvd to advertise this prefix.

Any other ? yes, your assumption is wrong. corrected. DHCPv6 (RFC3633) is the only IETF specified protocol mechanism for prefix delegation. you can possibly do it with TR-69, DOCSIS or manual configuration. cheers, Ole -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
