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.
