Configuring PIM-DM 135
Example: PIM-DM ConfigurationLS_A has a port carrying Vlan 10 to connect Multicast Source, a port carrying Vlan11 to connect LS_B and a port carrying Vlan12 to connect LS_C. Configure to implement multicast between Multicast Source and Receiver 1 and Receiver 2.

Figure 33 PIM-DM Configuration Networking

Configuration procedureThis section only provides the configuration for Switch A because the configuration procedures for Switch B and Switch C are similar. 1Enable the multicast routing protocol.
