12.2 IGMP Snooping
IGMP Snooping (Internet Group Management Protocol Snooping) is a constraint
mechanism on L2 devices to manage and control multicast groups. By analyzing the
IGMP messages received, L2 devices establish a mapping between ports and MAC
multicast addresses and forward the multicast data accordingly.
As shown below, multicast data are transmitted on L2 without IGMP snooping. When
IGMP snooping runs, known multicast group data are transmitted to specified receivers
while unknown multicast data are still on Layer 2.
12.2.1 Property
IGMP Snooping is on the L2 switch between the multicast routers and the user hosts,
applicable to deploy IPv4 networks. It is configured in a VLAN to snoop the IGMP/MLD
messages transmitted between routers and hosts, and to establish a L2 forwarding
table for multicast data, in order to manage and control the multicast data forwarding
in L2 network.
Global IGMP Snooping function should be enabled since it is disabled by default.
