With Internet Group Management Protocol (IGMP) snooping, Layer 2 devices also can make intelligent multicast forwarding decisions by examining the contents of each frameâs Layer 3 IP header. Consider the example of a heterogeneous Layer 2 and Layer 3 network that does not use IGMP snooping.ith Internet Group Management Protocol (IGMP) snooping, Layer 2 devices also can make intelligent multicast forwarding decisions by examining the contents of each frameâs Layer 3 IP header.
