Enabling the MLD snooping querier
About the MLD snooping querier
This feature enables the Layer 2 device to periodically send MLD general queries to establish and maintain multicast forwarding entries at the data link Layer. You can configure an MLD snooping querier on a network without Layer 3 multicast devices.
Restrictions and guidelines
Do not enable the MLD snooping querier on an IPv6 multicast network that runs MLD. An MLD snooping querier does not participate in MLD querier elections. However, it might affect MLD querier elections if it sends MLD general queries with a low source IPv6 address. For more information about MLD queries, see "Configuring MLD."
On a VXLAN network, the MLD snooping querier in a VSI does not include VLAN tags in MLD general queries. As a best practice, do not enable the MLD 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.
