PIM SPT Threshold Settings

This window is used to display 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.
