We had a conclusive discussion off this point during the interim WG meeting in Sunnyvale. The reasoning goes as follow: if we want to maximize interoperability, we want to have a single mandatory address configuration procedure, not two; everybody agrees that we must support stateless address configuration; thus we should make stateless mandatory, and other configuration methods optional. This is properly reflected in section 5.3 (nodes MAY support DHCPv6), in section 4.5.2 (MUST support stateless) and in the current text of section 4.5.5, which is just fine. -- Christian Huitema -------------------------------------------------------------------- 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] --------------------------------------------------------------------
