ipv6 mld snooping vlan
The configuration and the static ports and groups are saved in NVRAM.
When the IPv6 multicast router is a Catalyst 6500 switch and you are using extended VLANs (in the
range 1006 to 4094), IPv6 MLD snooping must be enabled on the extended VLAN on the Catalyst 6500
switch in order for the Catalyst 2350 switch to receive queries on the VLAN. For normal-range VLANs
(1 to 1005), it is not necessary to enable IPv6 MLD snooping on the VLAN on the Catalyst 6500 switch.
VLAN numbers 1002 through 1005 are reserved for Token Ring and FDDI VLANs and cannot be used
in MLD snooping.
Examples
This example shows how to enable MLD Immediate-Leave processing on VLAN 1:
Switch(config)# ipv6 mld snooping vlan 1 immediate-leave
This example shows how to disable MLD Immediate-Leave processing on VLAN 1:
Switch(config)# no ipv6 mld snooping vlan 1 immediate-leave
This example shows how to configure a port as a multicast router port:
Switch(config)# ipv6 mld snooping vlan 1 mrouter interface gigabitethernet0/2
This example shows how to configure a static multicast group:
Switch(config)# ipv6 mld snooping vlan 2 static FF12::34 interface gigabitethernet0/2
You can verify your settings by entering the show ipv6 mld snooping vlan vlan-id user EXEC
command.
