Description
Use
multicast-vlan
to configure the specified VLAN as a multicast VLAN and enter multicast VLAN view.
Use
undo multicast-vlan
to remove the specified VLAN as a multicast VLAN.
The VLAN to be configured is not a multicast VLAN by default.
The specified VLAN to be configured as a multicast VLAN must exist.
The multicast VLAN feature cannot be enabled on a device with IP multicast routing enabled.
For a sub-VLAN-based multicast VLAN, you must enable IGMP snooping only in the multicast VLAN. For
a port-based multicast VLAN, you must enable IGMP snooping in both the multicast VLAN and all the
user VLANs.
