11.4.7 Application Example for PIM SM
Network Requirements
1. Receivers receive VOD data through multicast. The whole network runs PIM SM as multicast
routing protocol.
2. Host A and Host D act as multicast receivers.
3. Switch A connects to Switch B in VLAN 2, connects to Switch C in VLAN 3. The Source server
connects to Switch A in VLAN 1.
4. Host A and B connect to Switch B in VLAN 4. Host C and D connect to Switch C in VLAN 5.
5. All switches run PIM SM. The VLAN interfaces connected to hosts run IGMP protocol.
6. Specify VLAN interface 3 in switch A as candidate BSR and candidate RP.
Network Diagram
The IP addresses of VLAN interfaces in each switch are displayed below:
Switch A: VLAN interface 1: 192.168.1.2/24
VLAN interface 2: 192.168.2.2/24
VLAN interface 3: 192.168.3.2/24
Switch B: VLAN interface 2: 192.168.2.100/24
VLAN interface 4: 192.168.4.100/24
Switch C: VLAN interface 3: 192.168.3.100/24
VLAN interface 5: 192.168.5.100/24
