28.4 PIM-DM Configuration Example
I. Networking 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.
