Enabling the IGMP snooping querier
This feature enables the device to periodically send IGMP general queries to establish and maintain multicast forwarding entries at the data link Layer. You can configure an IGMP snooping querier on a network without Layer 3 multicast devices.
Configuration restrictions and guidelines
When you enable the IGMP snooping querier, follow these restrictions and guidelines:
Do not enable the IGMP snooping querier on a multicast network that runs IGMP. An IGMP snooping querier does not take part in IGMP querier elections. However, it might affect IGMP querier elections if it sends IGMP general queries with a low source IP address.
On a VXLAN network, the IGMP snooping querier in a VSI does not include VLAN tags in IGMP general queries. As a best practice, do not enable the IGMP snooping querier in a VSI if the VSI uses the Ethernet access mode. For more information about the Ethernet access mode, see VXLAN Configuration Guide.
Configuration procedure
To enable the IGMP snooping querier for a VLAN or VSI:
Step | Command | Remarks |
