Configuring Multicast VLAN
Network requirements
As shown in Figure 44-4 , Workstation is a multicast source. Switch A forwards multicast data from the
multicast source. A Layer 2 device, Switch B forwards the multicast data to the end users Host A and
Host B.
Table 44-2 describes the network devices involved in this example and the configurations you should
make on them.
Table 44-2 Network devices and their configurations
Device Device description Networking description
Switch A Layer 3 device
The interface IP address of VLAN 20 is 168.10.1.1.
GigabitEthernet 1/0/1 is connected to the workstation and
belongs to VLAN 20.
The interface IP address of VLAN 10 is 168.10.2.1.
GigabitEthernet 1/0/10 belongs to VLAN 10. GigabitEthernet
1/0/10 is connected to Switch B.
Switch B Layer 2 device
VLAN 2 contains GigabitEthernet 1/0/1 and VLAN 3 contains
GigabitEthernet 1/0/2. The two ports are connected to Host A and
Host B, respectively.
VLAN 10 includes GigabitEthernet 1/0/10, GigabitEthernet1/0/1,
and GigabitEthernet 1/0/2. GigabitEthernet 1/0/10 is connected
to Switch A. VLAN 10 is a multicast VLAN.
Host A User 1 Host A is connected to GigabitEthernet 1/0/1 on Switch B.
Host B User 2 Host B is connected to GigabitEthernet 1/0/2 on Switch B.
Configure a multicast VLAN, so that users in VLAN 2 and VLAN 3 can receive multicast streams
through the multicast VLAN.

Configuration procedure
The following configuration is based on the prerequisite that the devices are properly connected and all
the required IP addresses are already configured.
1) Configure Switch A:
# Set the interface IP address of VLAN 20 to 168.10.1.1 and enable PIM DM on the VLAN interface.
