MLD Snooping Configuration Guidelines
When configuring MLD snooping, consider these guidelines:
• 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 3750-X or 3560-X 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 multicast entries allowed on the switch or switch stack is determined by
the configured SDM template.
• The maximum number of address entries allowed for the switch or switch stack is 1000.
Table 1-1 Default MLD Snooping Configuration
Feature Default Setting
MLD snooping (Global) Disabled.
MLD snooping (per VLAN) Enabled. MLD snooping must be globally enabled for VLAN
MLD snooping to take place.
IPv6 Multicast addresses None configured.
IPv6 Multicast router ports None configured.
MLD snooping Immediate Leave Disabled.
MLD snooping robustness variable Global: 2; Per VLAN: 0.
Note The VLAN value overrides the global setting. When the
VLAN value is 0, the VLAN uses the global count.
Last listener query count Global: 2; Per VLAN: 0.
Note The VLAN value overrides the global setting. When the
VLAN value is 0, the VLAN uses the global count.
Last listener query interval Global: 1000 (1 second); VLAN: 0.
Note The VLAN value overrides the global setting. When the
VLAN value is 0, the VLAN uses the global interval.
TCN query solicit Disabled.
TCN query count 2.
MLD listener suppression Disabled.
