Multicast Router Configuration If a multicast router is attached to the switch, its existence can be learned dynamically. You can also statically configure an interface as a multicast router interface, which is an interface that faces a multicast router or IGMP querier and receives multicast traffic. Use this screen to manually configure an interface as a static multicast router interface. 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 needed only when you want to make sure the multicast router always receives IGMP packets from the switch in a complex network.  To configure the multicast router mode for one or more interfaces: 1. Select Switching Multicast  IGMP Snooping  Multicast Router Configuration. 2. Select each interface to configure. 138
