M4200 -> M4300 Multicast Configuration (for NDI / Dante)

Hi...

Using 1.1.1.1 and 2.2.2.2 as querier addresses are not a concern as the addresses can be anything you wish, ie., they are not actual IP adreses, but used as part of an election process. Since there can only be a single querier active in the network, and if (as in your case), multiple
queriers are configured, this can trigger an election process. The current active querier will be the switch with the lowest address configured in the querier field.

The M4300 is the primary querier, so in the event of any M4300 downtime, the M4200 would then become the primary IGMP querier, etc.

In order to view Fast-Leave information, the following commands can be used for example:

#show igmpsnooping 1
#show igmpsnooping fast-leave (at port level)

Regarding running Dante and NDI devices on the same VLAN, the best practice recommendation would be to create a seperate VLAN for the Dante devices.
