Fig 2-12-1 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
switchA (config-vlan10)exit
switchA (config)#interface vlan 10
switchA(Config-if-Vlan10)#ip pim dense-mode
switchA(Config-if-Vlan10)#exit
switchA (config)#vlan 20
switchA (config-vlan20)#multicast-vlan
switchA (config-vlan20)#exit
switchA (config)#ip igmp snooping
switchA (config)#ip igmp snooping vlan 20
switchA (config)#interface vlan 20
switchA(Config-if-Vlan20)#ip pim dense-mode
switchA(Config-if-Vlan20)#exit
switchA (config)#ip pim multicast
