Configuring IPv6 MLD Snooping
Configuring IPv6 MLD Snooping
DETAILED STEPS
To remove a multicast router port from the VLAN, use the no ipv6 mld snooping vlan vlan-id mrouter interface
interface-id global configuration command.
EXAMPLE
This example shows how to add a multicast router port to VLAN 200:
Switch# configure terminal
Switch(config)# ipv6 mld snooping vlan 200 mrouter interface gigabitethernet0/2
Switch(config)# exit
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.
DETAILED STEPS
To disable MLD Immediate Leave on a VLAN, use the no ipv6 mld snooping vlan vlan-id immediate-leave global
configuration command.
Table 46-15
Command Purpose
1. configure terminal Enter global configuration mode.
2. ipv6 mld snooping vlan vlan-id mrouter
interface interface-id
Specify the multicast router VLAN ID, and specify the
interface to the multicast router.
 The VLAN ID range is 1 to 1001 and 1006 to 4094.
 The interface can be a physical interface or a port
channel. The port-channel range is 1 to 10.
3. end Return to privileged EXEC mode.
4. show ipv6 mld snooping mrouter [vlan
vlan-id]
Verify that IPv6 MLD snooping is enabled on the VLAN
interface.
5. copy running-config startup-config (Optional) Save your entries in the configuration file.
