I guess we are talking about "what is the best for ISP-to-Customer (PE-to-CPE) prefix delegation", correct? Then, there seems three proposals shown below for this purpose. What is your opinion for each proposed mechanism? (APD) draft-haberman-ipngwg-auto-prefix-02.txt (DHCPv6+PD option) draft-troan-dhcpv6-opt-prefix-delegation-00.txt (RA+PD option) draft-lutchann-ipv6-delegate-option-00.txt I believe everyone here agrees that zero-configuration environment is very important for the deployment of IPv6, because we know IPv6 should realize an world where not only technical people but also much more non-technical people can enjoy the global address and always-on environment. To achieve zero-configuration for "ISP-to-Customer (PE-to-CPE) prefix delegation", we had better have a global consensus about which mechanism is minimally required for this purpose. Many mechnisms for the same purpose will make it difficult to achieve zero-configuration enviroment, because CPE should know which to use before runnning an auto-configuration protocol among many choices. My opinion is: (APD) a good choice for a minimamlly required protocol for prefix delegation (DHCPv6+PD option) for those who want to more auto-configured parameters other than site-prefix (RA+PD option) can be used at only P-to-P enviroment and it is too restrictive P.S. Here is an ppt presentation about the "temporally" conclusion of IPv6 engineers mostly in Japan about this issue. http://www.apnic.net/meetings/13/sigs/docs/4.3_OSG_UNI.ppt It's a little old because there were no DHCPv6 nor RA proposals for prefix delegation when we discussed, but comments and opinions are very welcome. ---Toshi Yamasaki / NTT Communications -------------------------------------------------------------------- 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] --------------------------------------------------------------------
