Configuring MLDv2 Snooping
Note To use MLDv2 snooping, configure a Layer 3 interface in the subnet for IPv6 multicast routing or enable
the MLDv2 snooping querier in the subnet (see the “Enabling the MLDv2 Snooping Querier” section on
page 29-9).
These sections describe how to configure MLDv2 snooping:
• Enabling MLDv2 Snooping, page 29-10
• Configuring a Static Connection to a Multicast Receiver, page 29-11
• Enabling Fast-Leave Processing, page 29-13
• Configuring Explicit Host Tracking, page 29-14
• Configuring Report Suppression, page 29-14
• Displaying MLDv2 Snooping Information, page 29-15
Note Except for the global enable command, all MLDv2 snooping commands are supported only on VLAN
interfaces.
