  1. Configure an IP address for each interface and a unicast routing protocol.
  2. Enable all the VLAN interfaces as multicast interface, enable PIM-SM on all interfaces and enable IGMP on the interface that connects to the Receiver.
  3. Configure C-BSR and C-RPs on loopback interface.
  4. Configure the SPT switching condition to the multicast packets reached 120000 bytes in 10s.
