PIM snooping configuration example
Network requirements
As shown in
OSPF 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 Ten-GigabitEthernet 1/0/1. Router A, Router B, Router C, and
•
Router D run PIM-SM.
Ten-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.
