GS748T Smart Switch
Multicast Router Configuration
This page configures the interface as the one the multicast router is attached to. All IGMP
packets snooped by the switch will be forwarded to the multicast router reachable from this
interface. The configuration is not needed most of the time since the switch will automatically
detect the presence of multicast router and forward IGMP packet accordingly. It is only
needed when you want to make sure the multicast router always receives IGMP packets from
the switch in a complex network.
