Commenti

I router multicast inviano messaggi Group Membership Query per scoprire quali gruppi hanno membri in ognuna delle reti fisiche collegate. I computer host rispondono a un messaggio di query sull'appartenenza al gruppo inviando un report di appartenenza al gruppo per ogni gruppo multicast aggiunto dall'host. Un computer host può anche inviare un report di appartenenza al gruppo quando viene aggiunto a un nuovo gruppo multicast. I messaggi di riduzione dell'appartenenza al gruppo vengono inviati quando un computer host lascia un gruppo multicast.
