3. In normal circumstances, Receiver receives multicast data from Source through the path
Switch A-Switch B, which is the same as the unicast route.
4. After the configuration takes effect, Receiver will receive multicast data from Source through
the path Switch A-Switch C-Switch B.
 Network Diagram
 Configuration Procedure
1) Configure the interfaces and unicast routing protocol
Configure the VLAN interfaces and their IP addresses of Switch A, Switch B and Switch C on the
page Routing→ Interface→ Interface Config according to the topology,
Configure the OSPF features on the switches in this PIM DM domain, making the switches
accessible with each other at the network layer. Detailed configuration process is omitted here.
2) Configure the multicast routing features
