Description
Enable or disable the IGMP snooping querier function.
On an IP multicast network that runs IGMP, a Layer 3 device acts as an IGMP
querier to send IGMP queries and establish and maintain multicast forwarding
entries, ensuring correct multicast traffic forwarding at the network layer.
On a network without Layer 3 multicast devices, IGMP querier cannot work
because a Layer 2 device does not support IGMP. To address this issue, you can
enable IGMP snooping querier on a Layer 2 device so that the device can
generate and maintain multicast forwarding entries at the data link layer,
providing IGMP querier functions.
Configure the IGMP query interval.
Specify the source IP address of general queries.
Specify the source IP address of group-specific queries.
