460 CHAPTER 43: PIM-DM CONFIGURATION
PIM-DM Configuration
Example
Network requirements
Lanswitch1 is connected to the multicast source through VLAN-interface 10,
connected to Lanswitch2 through VLAN-interface 11 and connected to
Lanswitch3 through VLAN-interface 12. Through running PIM-DM, you can
implement multicast among RECEIVER 1, RECEIVER 12 and Multicast Source.
