Configuring the MLD Snooping Version

Configuring the MLD Snooping Version


The Multicast Listener Discovery (MLD) protocol maintains group memberships between Layer 3 multicast devices and user hosts. Two versions are available: v1 and v2. After the MLD version is configured on the Layer 2 device, the device can process the MLD packets of the specified version. The MLD versions on the Layer 2 device and Layer 3 multicast device must be the same. If MLD is disabled on the Layer 3 multicast device, the MLD version on the Layer 2 device must be the same as or higher than that on user hosts.

If the user hosts in a VLAN support different MLD versions, the Layer 2 device must be able to process the MLD packets of all these versions.
