3Com 5500-SI - Displaying and Debugging PIM-DM; PIM-DM Configuration Example

338 CHAPTER 18: MULTICAST PROTOCOL
Displaying and
Debugging PIM-DM
After the above configuration, execute the display command in any view to display
the running of PIM-DM configuration, and to verify the effect of the configuration.
Execute the
debugging command in user view for the debugging of PIM-DM.
PIM-DM Configuration
Example
Networking Requirements
Switch_A has a port carrying Vlan 10 to connect the Multicast Source, a port carrying
Vlan11 to connect Switch_B and a port carrying Vlan12 to connect to Switch_C.
Configure to implement multicast between Multicast Source and Receiver 1 and
Receiver 2.
