IGMP snooping configuration

Internet Group Management Protocol (IGMP) snooping is a multicast constraining mechanism that runs

on Layer 2 devices to manage and control multicast groups.
By analyzing received IGMP messages, a Layer 2 device that is running IGMP snooping establishes
mappings between ports and multicast MAC addresses and forwards multicast data based on these

mappings.
As shown in

, when IGMP snooping is not running on the switch, multicast packets are flooded

to all devices at Layer 2. However, when IGMP snooping is running on the switch, multicast packets for

known multicast groups are multicast to the receivers, rather than broadcast to all hosts, at Layer 2.

Figure 106

Multicast forwarding before and after IGMP snooping runs

IGMP snooping sends Layer 2 multicast packets to the intended receivers only. This mechanism provides

the following advantages:

•

Reducing Layer 2 broadcast packets and saving network bandwidth

•

Enhancing the security of multicast packets

•

Facilitating the implementation of accounting for each host

NOTE:

For more information about IGMP snooping, see
