To statically specify or view a port in a VLAN, use the following commands:
1. Statically specify a port in a VLAN as connected to a multicast router.

2. View the ports that are connected to multicast routers.
EXEC Privilege mode

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 configure 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
Display the MLD Snooping Table
1. To display the MLD snooping table, use the following command:
EXEC Privilege
show ipv6 mroute snooping vlan
2. To display the group information in the table, use the following command:
EXEC Privilege
show ipv6 mld snooping groups
