To configure an IGMP proxy, you will need to perform the following tasks: Before configuring an When you enable IGMP IGMPv3 join and leave enabling a PIM on an interface enables IGMPv2 on that device. When a subscriber changes channels or turns off the television, the set-top box sends an IGMP leave message for the multicast type and With source filtering, we can join multicast groups but only from specified source addresses.
