Criminals can take advantage of this safe leak and flood individual hosts or the entire network with multicast packets to break them down, just like a typical DoS/DDoS attack. And IGMP Snooping controls these multicast groups by snooping and analyzing the multicast packets exchanged between the upstream Layer 3 multicast device and downstream hosts, so as to effectively suppress the unnecessary forwarding of multicast data in Layer 2 networks. Update the default timer value of 5 in the following conditions: You suspect membership queries or reports are being lost on the network. IGMP snooping is an important feature of network switches.
