Specify the PIM RP Threshold That Triggers Source-Specific Switching

You can specify the number of registered packets that must have been received for the RP to initiate switching to the source-specific SPT.

1. Specify how many packets will trigger the RP to switch to a source-specific SPT.

   SEFOS# configure terminal
   SEFOS(config)# set ip pim enable
   SEFOS(config)# set ip pim rp-threshold 10
   SEFOS(config)# end
   

   This example switch the RP to the source-specific shortest path tree after 10 registered packets are received.

2. Ensure that the correct number of packets have been set.

   SEFOS# show ip pim thresholds
