Fig 12-1 The function configuration of multicast VLAN
As showed in the picture above, multicast server connects to a 3-layer switch
switchA via port 0/0/1,and the port 0/0/1 belongs to the vlan10 of the switch. 3-lay switch
switchA connects to 2-layer switch switchB via port . Vlan 20 is a multicast vlan. The vlan
100 of switchB includes port 0/0/15，vlan101 includes port 0/0/20. PC1 and PC2 connect
to port 0/0/15 and respectively. switchB connects to switchA via port . Vlan20 is a
multicast vlan.
By configuring multicast VLAN, we can make PC1 and PC2 to receive multicast data
viamulticast VLAN.
The following configuration is based on the assupmtion that the IP address of
switchA has been configured, and the devices are connected correctly.
The following is the configuration procedure:
SwitchA#config
SwitchA (config)#vlan 10
SwitchA (config-vlan10)#switchport access ethernet 0/0/1
SwitchA (config-vlan10)exit
SwitchA (config)#vlan 20
SwitchA (config-vlan20)#exit
SwitchA (config)#ip igmp snooping
SwitchA (config)#ip igmp snooping vlan 20
SwitchA (config)# interface ethernet 0/0/10
SwitchA (Config-Ethernet0/0/10)switchport mode trunk
SwitchB#config
