Multicast snooping is a way for a Layer 2 device to snoop at the Layer 3 packet content
to determine which actions are to be taken to process or forward a frame. There are
specific forms of snooping, such as IGMP snooping or PIM snooping. In all cases, snooping
involves a device configured to function at Layer 2 having access to Layer 3 (packet)
information. Snooping makes multicasting more efficient in these devices.
