Command Usage
â—† If enabled, the switch will serve as querier if elected. The querier is responsible
for asking hosts if they want to receive multicast traffic.
â—† An IPv6 address must be configured on the VLAN interface from which the
querier will act if elected. When serving as the querier, the switch uses this IPv6
address as the query source address.
â—† The querier will not start or will disable itself after having started if it detects an
IPv6 multicast router on the network.
Example
Console(config)#ipv6 mld snooping querier
Console(config)#
