as one of the authors of RFC3633, DHCP PD was not designed to do assignment of prefixes inside a network. DHCP PD was designed to be a "fax replacement". there has been a number of proposals for how DHCP PD could be adapted for this purpose: they generally fall into one of flat assignment with central DHCP server or hierarchical PD with a spanning tree of DHCP relays. http://tools.ietf.org/html/draft-baker-homenet-prefix-assignment-01 http://tools.ietf.org/html/draft-chakrabarti-homenet-prefix-alloc-01 http://tools.ietf.org/html/draft-gmann-homenet-relay-autoconf-01 http://tools.ietf.org/html/draft-grundemann-hipnet-00 please take a look at those drafts, and let us know what we've missed in the DHCP PD "solution space". cheers, Ole
