When an IGMP snooping switch is not acting as a querier, it sends out the general query in response to the MSTP triggered link-layer
topology change, with the source IP address of 0.0.0.0 to avoid triggering querier election.
Designating a Multicast Router Interface
To designate an interface as a multicast router interface, use the following command.
The 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
trac originating from receivers is forwarded to multicast router interfaces.
• Designate an interface as a multicast router interface.
