Switch# configure terminal
Switch(config)# ipv6 mld snooping vlan 200 mrouter interface gigabitethernet0/2

Enabling MLD Immediate Leave

When you enable MLDv1 Immediate Leave, the switch immediately removes a port from a multicast group when it detects
an MLD Done message on that port.
BEFORE YOU BEGIN
You should only use the Immediate-Leave feature when there is a single receiver present on every port in the VLAN.
When there are multiple clients for a multicast group on the same port, you should not enable Immediate-Leave in a
VLAN.
