Usage Guide:
After a VLAN is associated with the multicast VLAN, when there comes
the multicast order in the port of this VLAN, then the multicast data will be sent from the
multicast VLAN to this port, so to reduce the data traffic. The VLAN associated with the
multicast VLAN should not be a Private VLAN. A VLAN can only be associated with
another VLAN after the multicast VLAN is enabled. Only one multicast VLAN can be
enabled on a switch.
Examples:
Switch(config)#vlan 2
Switch (Config-Vlan2)#multicast-vlan
Switch (Config-Vlan2)# multicast-vlan association 3;4
16.4 Examples Of Multicast VLAN
Fig 16-1 Function configuration of the Multicast VLAN
As shown in the figure, the multicast server is connected to the layer 3 switch
switchA through port 1/1 which belongs to the vlan10 of the switch. The layer 3 switch
switchA is connected with layer 2 switches through the port 1/10. the Vlan20 is a
multicast vlan. On the switchB the vlan100 is configured set to contain port 1/15, and
vlan101 to contain port 1/20. PC1 and PC2 are respectively connected to port 1/15 and
1/20. The switchB is connected with the switchA through port 1/10. vlan 20 is a multicast
vlan. By configuring multicast vlan, the PC1 and PC2 will receives the multicast data from
the multicast VLAN.
Following configuration is based on the IP address of the switch has been configured
and all the equipment are connected correctly .
