I was discounting the reason (the already IPv6 installed base) you gave. the MUST is for newer IPv6 CN implementations. as I told you already, it makes the MN's life easier. but the current spec does ensure that a MN can still have a session with an old IPv6 implementation (which does not implement HAO) through reverse tunneling. so again, where is the problem? why are you against the MUST? regards Vijay -------------------------------------------------------------------- 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] --------------------------------------------------------------------
