it is not new at all. hosts have been running routing protocol daemons for a long time (sometimes it was only listening, like "routed -q"). >Generally, hosts already support MLD/IGMP in order to join multicast >groups, so why require them to run a routing protocol? at this moment no client implementation issues MLD join for anycast address, so it is a large change to make. itojun -------------------------------------------------------------------- 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] --------------------------------------------------------------------
