7.2.10 Set the Threshold of Switchover from the RPT to the SPT

The PIM-SM router uses the shared tree to forward multicast data packets initially. If the
rate of the multicast data exceeds the threshold, the last hop router the packet passes
will initiate a switch from the shared tree to the shortest path tree.
Perform the following configuration in PIM view.
Table 7-9 Set the threshold of switchover from the RPT to the SPT
Set the threshold of switchover
from the RPT to the SPT
Restore the default setting
By default, the threshold is 0. That is, the last hop router initiates the switch to the
shortest path tree upon the arrival of the first multicast data packet.

7.3 Display and Debug PIM-SM

After the above configuration, execute display command in any view to display the
running of PIM-SM configuration, and to verify the effect of the configuration.
Execute debugging command in user view for the debugging of PIM-SM.
