Designating a Multicast Router Interface
To designate an interface as a multicast router interface, use the following command.
Dell Networking OS also has the capability of listening in on the incoming IGMP general queries and
designate those interfaces as the multicast router interface when the frames have a non-zero IP source
address. All IGMP control packets and IP multicast data traffic originating from receivers is forwarded to
multicast router interfaces.
