Description
Enable or disable MLD snooping in the VLAN.
You can proceed with the subsequent configurations only if Enable is selected here.
The default setting is MLDv1.
By configuring an MLD snooping version, you actually configure the versions of MLD
messages that MLD snooping can process.
•
MLDv1 snooping can process MLDv1 messages, but it floods MLDv2 messages in
the VLAN instead of processing them.
•
MLDv2 snooping can process MLDv1 and MLDv2 messages.
IMPORTANT:
If you change the MLDv2 snooping to MLDv1 snooping, the system clears all MLD
snooping forwarding entries that are dynamically added.
Enable or disable the MLD snooping querier function.
In an IPv6 multicast network that runs MLD, a Layer 3 device acts as the MLD querier
to send MLD queries and establish and maintain IPv6 multicast forwarding entries,
ensuring correct IPv6 multicast traffic forwarding at the network layer.
On an IPv6 network without Layer 3 multicast devices, MLD querier cannot work
because a Layer 2 device does not support MLD. To address this issue, you can
enable MLD snooping querier on a Layer 2 device so that the device can generate
and maintain IPv6 multicast forwarding entries at data link layer, providing MLD
querier functions.
Configure the MLD general query interval.
Specify the source IPv6 address of MLD general queries.
Specify the source IPv6 address of MLD multicast-address-specific queries.
