520 CHAPTER 36: CONFIGURING PIM-SM
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 Example In the actual network, because different manufacturers provide routing
equipment, 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.
