4.17.2 Example for Configuring SPT Switchover in PIM-SM
Domain
Networking Requirements
Receivers can receive the VOD information in multicast mode. The entire PIM network adopts
a single BSR administrative domain. By default, after receiving the first multicast data packet,
the RP and the DR on the receiver side perform the SPT switchover, finding the optimal path to
receive the multicast information from the multicast source. If the receiver requires that the SPT
switchover be performed after the traffic reaches the threshold, you need to configure the SPT
switchover function.
As shown in Figure 4-3, you need to configure the S9300s properly. In this way, HostA on the
leaf network then can receive multicast data from the RP (GE1/0/0 of S9300-A). When the
transmission rate of multicast packets reaches 1024 kbit/s, the SPT switchover is performed.
After the SPT switchover, the path through which HostA receive multicast packets is Source--
S9300-B--S9300-C--HostA.
