2.4.2 Example 2
Configure multicast VLAN on Layer 2 and Layer 3 switches.
I. Network requirements
The multicast source is Workstation. Switch A forwards the multicast data flows that the
multicast source sends. The multicast data flows are forwarded by the Layer 2 switch
Switch B to the end user PC1 and PC2.
Table 2-15 describes the network devices involved in this example and the
configurations you should make on them.

Device Description
Switch A Layer 3 switch
The interface IP address of VLAN 20 is 168.10.1.1.
Ethernet1/0/1 is connected to the workstation and
belongs to VLAN 20.
VLAN 10 is the multicast VLAN.
Ethernet1/0/5 belongs to VLAN 2, Ethernet1/0/6
belongs to VLAN 3, and Ethernet1/0/10 is
connected to Switch B.
Switch B Layer 2 switch
VLAN 2 contains Ethernet1/0/1 and VLAN 3
contains Ethernet1/0/2. The two ports are
connected to PC1 and PC2, respectively.
Ethernet1/0/10 is connected to Switch A.
PC 1 User 1 PC1 is connected to Ethernet1/0/1 on Switch B.
PC 2 User 2 PC2 is connected to Ethernet1/0/2 on Switch B.
Configure a multicast VLAN, so that the users in VLAN 2 and VLAN 3 can receive
multicast streams through the multicast VLAN.
