This seems like a bad design tradeoff to me. We already have a highly optimised mode of operation in MIPv6 (RO), and if you're not using it you are falling back to something less efficient. Your tradeoff improves the fallback solution a bit, but doesn't improve the optimised solution. And the cost is extreme: we need a new global infrastructure (though I admit some of it will be built anyway), MIPv6 deployment is delayed, most if not all small sites and homes will not be able to benefit from RO, etc. Jari -------------------------------------------------------------------- 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] --------------------------------------------------------------------
