Multicast Router VLAN Configuration
This page configures the interface to only forward the snooped IGMP packets that come from
the specified VLAN to the multicast router attached to this interface. The configuration is not
needed most of the time since the switch will automatically detect the presence of a multicast
router and forward IGMP packets accordingly. It is only needed when you want to make sure
that the multicast router always receives IGMP packets from the switch in a complex network.
