shows the default MLD snooping configuration.
Default MLD Snooping Configuration
You can configure MLD snooping characteristics at any time, but you must globally enable MLD
snooping by using the ipv6 mld snooping global configuration command for the configuration to
take effect.
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 2960, 2960-S, or 2960-C 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.
MLD snooping and IGMP snooping act independently of each other. You can enable both features
at the same time on the switch.
The maximum number of address entries allowed for the switch stack is 1000.
