Yes, should have remembered that. Mine does that, I wonder if that is the only one with this feature.. :-) But, for any other useful traffic, the source address is there, and implicitly defines the group. A snooping switch would be foolish not to utilize this easily available info for updating it's soft state. -------------------------------------------------------------------- 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] --------------------------------------------------------------------
