MLD Snooping must be enabled globally before it can be enabled in a VLAN.
After enabling MLD Snooping in a VLAN, you cannot enable MLD and/or IPv6 PIM on the
corresponding VLAN interface, and vice versa.
When you enable MLD Snooping in a specified VLAN, this function takes effect for ports in this
VLAN only.
Configuring the Version of MLD Snooping
By configuring the MLD Snooping version, you actually configure the version of MLD messages that
MLD Snooping can process.
MLD Snooping version 1 can process MLDv1 messages, but cannot analyze and process MLDv2
messages, which will be flooded in the VLAN.
MLD Snooping version 2 can process MLDv1 and MLDv2 messages.
Follow these steps to configure the version of MLD Snooping:
To do...
Enter system view
Enter VLAN view
Configure the version of MLD
Snooping
If you switch MLD Snooping from version 2 to version 1, the system will clear all MLD Snooping
forwarding entries from dynamic joining, and will:
Keep forwarding entries from version 2 static (*, G) joining;
Clear forwarding entries from version 2 static (S, G) joining, which will be restored when MLD
Snooping is switched back to version 2.
For details about static joining, refer to
