Configuring IPv6 MLD Snooping
Configuring IPv6 MLD Snooping
You can enable and disable MLD snooping on a per-VLAN basis or for a range of VLANs, but if you globally disable MLD
snooping, it is disabled in all VLANs. If global snooping is enabled, you can enable or disable VLAN snooping.
Enabling MLD Snooping
DETAILED STEPS
Command
1. configure terminal
2. ipv6 mld snooping
3. end
4. copy running-config
startup-config
5. reload
To globally disable MLD snooping on the switch, use the no ipv6 mld snooping global configuration command.
EXAMPLE
This example shows how to enable MLD snooping globally:
Switch(config)# ipv6 mld snooping
Enabling MLD Snooping on a VLAN
DETAILED STEPS
Note: 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 this 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.
Command
1. configure terminal
2. ipv6 mld snooping
3. ipv6 mld snooping vlan vlan-id
4. end
5. copy running-config startup-config
To disable MLD snooping on a VLAN interface, use the no ipv6 mld snooping vlan vlan-id global configuration command
for the specified VLAN number.
EXAMPLE
This example shows how to enable MLD snooping on a VLAN:
Table 46-12
Table 46-13
Purpose
Enter global configuration mode.
Globally enable MLD snooping on the switch.
Return to privileged EXEC mode.
(Optional) Save your entries in the configuration file.
Reload the operating system.
Purpose
Enter global configuration mode.
Globally enable MLD snooping on the switch.
Enable MLD snooping on the VLAN.The VLAN ID range is 1
to 1001 and 1006 to 4094.
Note: MLD snooping must be globally enabled for VLAN
snooping to be enabled.
Return to privileged EXEC mode.
(Optional) Save your entries in the configuration file.
