Step 3 Configure the static RP.
# Configure the static RP on S9300-A, S9300-B, and S9300-C. The configurations of S9300-B
and S9300-C are similar to configuration of S9300-A, and are not mentioned here.
[S9300-A] pim
[S9300-A-pim] static-rp 192.168.1.1
Step 4 Configure the threshold of the SPT switchover.
# Configure S9300-C to perform the SPT switchover when the transmission rate of multicast
packets reaches 1024 kbit/s.
[S9300-C] pim
[S9300-C-pim] spt-switch-threshold 1024
[S9300-C-pim] quit
Step 5 Verify the configuration.
# The multicast source begins to send data to the multicast group, and HostA can receive the
data from the source. When the rate is smaller than 1024 kbit/s, you can run the display pim
routing-table command to view the PIM multicast routing table on S9300-C. You can find that
the upstream neighbor is S9300-A. The displayed information is as follows:
