Hello, I use the bridge tools on a debian with 5 interfaces. I want to use the multicast protocol with it. But by default, the bridge broadcast the multicast packet. Do you have any implementation of protocole like IGMP snooping or MGRP on bridge tools? I would like something like that : If nobody send a IGMP packet to join a multicast group, the multicast traffic is forbidden. In the other case, the bridge allow the traffic on the port where it recieve the IGMP packet (JOIN). Best Regards
