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… 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 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 more information about static joining, see “ Configuring static ports .”
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.
