Enable Snooping Explicit Tracking
The switch can be a querier, and therefore also has an option of updating the group table through explicit-tracking. Whether the switch is
the querier or not, if snooping is enabled, the switch tracks all the MLD joins. It has a separate explicit tracking table which contains group,
source, interface, VLAN, and reporter details.
1 To congure the system to remove the group immediately after receiving a Leave message, use the following command:
INTERFACE VLAN Mode
ipv6 mld snooping explicit-tracking
2 To display the MLD explicit-tracking table, use the following command.
EXEC Pivilege
show ipv6 mld snooping groups explicit
