PIM SPT Threshold Settings
This window is used to view and configure the PIM SPT threshold settings. Use this feature on the last
hop of the router. In the PIM-SM mode, initially the multicast traffic from the source will be flowing along
the RPT share tree to the receiver. After the first packet arrives at the last hop router, for each group of
traffic, it can operate in one of the following two modes. With the mode Infinity, the traffic keeps following
the share tree. With the mode 0, the source tree will be established and the traffic switchover to the
source tree.
To view the following window, click L3 Features > IP Multicast Routing Protocol > PIM > PIM for IPv4

hosts.
