Configuring MLD Multicast Router Interfaces
An MLD multicast router must exist to manage the MLD clients in a VLAN. For each
VLAN that supports MLD snooping, the switch must be statically configured with
or dynamically learn one or more interfaces where there is an MLD multicast
router. The interface that has an MLD router is known a MLD Multicast router
Interface. A VLAN that is MLD snooping-enabled must have one or more MLD
multicast router interfaces. An MLD multicast router can serve one or more VLANs.
To enable a switch port or LAG as an MLD Mrouter interface:
STEP 1 Click Multicast > MLD Mrouter in the navigation window.
By default, the MLD MRouter Table lists each switch port. To show LAGs, select
LAG from the Interface Type list.
STEP 2 Select the port or LAG to configure and click Edit.
STEP 3 Select Enable for the Mode.
STEP 4 Move VLAN IDs between the Available and Selected lists. VLANs in the Selected
list use this port or LAG as the MLD Mrouter interface.
• To select a VLAN: Click a VLAN in the Available list, and then click the right-
arrow button to move it to the Selected list.
• To remove a VLAN: Click a VLAN in the Selected list, and then click the left-
arrow button to move it to the Available list.
STEP 5 Click Apply and then click Close.
In the MLD Mrouter Table, the interface displays Enable in the Mode column and
lists the included VLANs.
