After the above configuration, execute the display command in all views to display PIM-SM configuration, and to verify the effect of the configuration. Executethe debugging command in system view for the debugging of PIM-SM.

PIM-SM Configuration In the actual network, because different manufacturers provide routing

Exampleequipment, the routing protocols are different. Because the PIM protocol is independent of any specific unicast protocol, there is no need to pay attention to the unicast protocol. The the purpose of this example, the routers are mutually accessible.
