Internet Group Management Protocol (IGMP)
IGMP allows for managing a single upstream interface and multiple
downstream interfaces of the IGMP/MLD (Multicast Listener
Discovery)-based forwarding. This function enables the system
to send IGMP host messages on behalf of hosts that the system
discovers through standard IGMP interfaces. Also, IGMP snooping
allows an Ethernet switch to “listen in” on the IGMP conversation
between hosts and routers, while IGMP querier will send out
periodic IGMP queries.
To enable this function:
1. Choose the IGMP interfaces by clicking on the check boxes
on the screen.
