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.
• MLDv1 snooping can process MLDv1 messages, but cannot analyze or process MLDv2 messages,
which will be flooded in the VLAN.
• MLDv2 snooping can process MLDv1 and MLDv2 messages.
Follow these steps to configure the version of MLD snooping:
To do… Use the command… Remarks
Enter system view system-view —
Enter VLAN view vlan vlan-id —
Configure the version of MLD
snooping
mld-snooping version version-
number
Optional
Version 1 by default
CAUTION:
If you change MLDv2 snooping to MLDv1 snooping, the system clears all MLD snooping forwarding
entries that the system adds dynamically, and also does the following:
Keeps static MLDv2 snooping forwarding entries (*, G)
Clears static MLDv2 snooping forwarding entries (S, G), which will be restored when MLDv1
snooping is changed back to MLDv2 snooping

Configuring IPv6 static multicast MAC address entries
In Layer-2 multicast, a Layer-2 IPv6 multicast protocol—such as MLD snooping—can dynamically add
IPv6 multicast MAC address entries. You can also configure IPv6 multicast MAC address entries.
