I agree. Moreover, you can't use it when you assume a site-boundary between a WAN port and LAN ports of CPE. > - pppext might be workable for PPP connections, and is a valid mechanism > especially if there is no simple alternative (e.g. if the only alternative > is full statefull DHCPv6). No. PPPext solves the issue only when you use PPP. That means you need another solution when you don't use PPP, and that makes it difficult to achieve zero-configuration enviroment. > - dhcpv6 will work ok, I think, but is a bit complex for being usable > in every scenario Yes, that's why Ralf proposed the DHCP subset or DHCP-lite named "DNCP". > - APD w/ ICMPv6 is ok but can be simplified (e.g. removing prefix return > message) I think APD is simple enough, and DNCP is also simple enough. Technically there is almost no difference between DNCP and APD. > - RA (Lutchansky) is a nice hack, kinda works with hacking. It assumes only P-to-P enviroment. Again you need another solution for non-P-to-P enviroment. Our goal is to achieve auto-configuration, right? Then, how dose a CPE know whether it is conneted to P-to-P link or P-to-MP link automatically? > Note that IMO, configuring these with "stateless DHCPv6" but obtaining the > prefix with e.g. APD makes perfect sense -- there might be reluctance to > implement full DHCP, or even the minimal set of "stateful" DHCP. Both APD and DNCP are "stateful". I'm providing commercial IPv6 services today, and will start IPv6 over DSL/FTTH services soon. You should understand that "stateful" is one of the most important requirements of commercial ISPs. How do you charge and/or solve abuse problems while you don't know who used which prefixes and when? -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
