Chapter 29 Configuring IPv6 Multicast Listener Discovery Snooping
Configuring IPv6 MLD Snooping
configuration command. The default is to send two queries. The switch also generates MLDv1 global
Done messages with valid link-local IPv6 source addresses when the switch becomes the STP root in the
VLAN or when it is configured by the user. This process is similar to that in IGMP snooping.
Configuring IPv6 MLD Snooping
These sections describe how to configure IPv6 MLD snooping:
• Default MLD Snooping Configuration, page 29-5
• MLD Snooping Configuration Guidelines, page 29-6
• Enabling or Disabling MLD Snooping, page 29-6
• Configuring a Static Multicast Group, page 29-7
• Configuring a Multicast Router Port, page 29-7
• Enabling MLD Immediate Leave, page 29-8
• Configuring MLD Snooping Queries, page 29-9
• Disabling MLD Listener Message Suppression, page 29-10
Default MLD Snooping Configuration
Table 29-1 shows the default MLD snooping configuration.
Table 29-1 Default MLD Snooping Configuration
Feature Default Setting
MLD snooping (Global) Disabled.

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.
