Host membership queries are sent by router to the all multicast address: 224.0.0.1. These queries use 0.0.0.0 in
the IGMP GDA field. A host for each group must respond to that query or the router will stop forwarding the traffic
for that GDA to that segment (after 3 attempts). The router simply keeps a multicast routing entry for each source
and links it to a list of outgoing interfaces (interface from where the IGMP report came). After three IGMP query
attempts with no answer, this interface is erased from outgoing interface list for all entries linked to that GDA.
Note: IGMPv1 has no leave mechanism. If a host no longer wants to receive the traffic, it simply quits. If it is the

IGMPv2 Membership Report
Leave Group when a host wants to leave a group, it should send a Leave Group IGMP message to destination
224.0.0.2 (instead of leaving silently like in IGMPv1)
last, the router will not have any answers to its query and will delete the GDA for that subnet.
