PIM snooping configuration example
Network requirements
As shown in Figure 16:
• RIP runs on the network.
• Source 1 sends multicast data to multicast group 224.1.1.1, and Source 2 sends multicast data
to multicast group 225.1.1.1.
• Receiver 1 belongs to multicast group 224.1.1.1, and Receiver 2 belongs to multicast group
225.1.1.1.
• Router C and Router D run IGMP on GigabitEthernet 1/0/1. Router A, Router B, Router C, and
Router D run PIM-SM.
• GigabitEthernet 1/0/2 on Router A acts as a C-BSR and a C-RP.
Configure IGMP snooping and PIM snooping on Switch A so that Switch A forwards PIM messages
and multicast data to only the routers that are interested in the multicast data.

Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 16. (Details not
shown.)
2. Configure RIP on all the routers. (Details not shown.)
