Which versions of IGMP Snooping are supported by Dante?

The correct answer is that Dante supports IGMP Snooping versions 2 and 3.

IGMP (Internet Group Management Protocol) is crucial for managing multicast group memberships within a network, which is particularly important for applications like Dante that rely heavily on efficient multicast data distribution.

Version 2 of IGMP introduced features for group membership queries, allowing routers to manage multicast IP address subscriptions more effectively. It enables more efficient use of network resources by ensuring that multicast traffic is only forwarded to ports with active listeners.

Version 3 added even more functionality, allowing for source-specific multicast, where hosts can join a multicast group from specific sources only. This is particularly beneficial in complex audio networks like those using Dante, as it allows for greater control over audio streams and reduces unnecessary traffic on the network.

By supporting both versions 2 and 3, Dante provides flexibility and optimization for different network configurations and applications, while still ensuring efficient multicast management. This capability is essential in maintaining high-quality audio transmission and minimizing latency in a Dante-equipped environment.
