Operation Manual – MulticastH3C S7500 Series Ethernet Switches Chapter 7 PIM Configuration7-187.6 PIM Configuration Examples7.6.1 PIM-DM Configuration ExampleI. Network requirementsLanswitch1 is connected to the multicast source through VLAN-interface 10, toLanswitch2 through VLAN-interface 11 and to Lanswitch3 through VLAN-interface 12.Through PIM-DM, multicast is implemented among Receiver 1, Receiver 2 and themulticast source.II.
