within the multicast VLAN, and also guarantees the security because the multicast
VLAN is completely isolated from the user VLANs.
Note:
Isolate VLANs cannot be set as multicast VLANs.
One port belongs to one multicast VLAN only.
The type of ports connecting to the user terminal must be hybrid.
The multicast member port must be in the same multicast VLAN with the router port.
Otherwise, the port cannot receive multicast packets.
If a router port is added to a multicast VLAN, the router port must be set as a trunk
port or tagged hybrid port. Otherwise, all the multicast member ports in this multicast
VLAN cannot receive multicast packets.
If a multicast member port needs to receive packets forwarded by the router port
which does not belong to any multicast VLAN, the multicast member port must be
removed from the multicast VLAN. Otherwise, the port cannot receive multicast
packets.
Example
# Configure VLAN 2 as a multicast VLAN.
<Quidway> system-view
System View: return to User View with Ctrl+Z.
