Configures all sources to use the shared rendezvous point (RP) tree instead of the Shortest Path Tree (SPT).
By default, the SPT is used for sending packets.
Router PIM configuration mode
This command uses only the RP to send packets and does not switch over to SPT.
The no spt-threshold infinity form of the command resets the default setting and uses SPT for sending packets.
This example configures all sources to use the shared RP tree for IPv4 PIM.
device(config)# router pim device(config-pim-router)# spt-threshold infinity
