5.3.4.9 IGMP
IGMP Snooping is used for multicast management and control. When the Ethernet
switch of the second layer receives the IGMP packets transmitted between the
host and router, IGMP Snooping will analyze the packets to establish and maintain
the address table of the MAC multicast, and then the routing multicast packets will
be transmitted according to the address table of MAC multicast. In this way, it
dramatically reduces the service flood on the receiving interface of unregistered
multicast group.
The IGMP proxy can make the PLC wireless router intercept the IGMP message
of host via the LAN interface, and then the IGMP message of host is transmitted
via the WAN interface. After IGMP proxy is enabled, the PLC wireless router works
as the agent server of host.
