PIM snooping configuration example
Network requirements
As shown in Figure 20 , Source 1 and Source 2 are connected to Router A and Router B, and Receiver 1
and Receiver 2 are connected to Router C and Router D, respectively.
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 their interface GigabitEthernet 1/0/1. Router A,
Router B, Router C, and Router D run PIM-SM, and interface GigabitEthernet 1/0/2 on Router A acts as
a C-BSR and 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.
