If the existing PIM neighbors exceed the configured value during configuration, 
they are not deleted.

Perform the following configuration in user view.

Execute the display command in all views to display the operation of the PIM-DM 
configuration, and to verify the effect of the configuration.

Execute the debugging command in user view for the debugging of PIM-DM.

LS_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.
