S9300s configured with default values can work normally. You can change the values of relevant
parameters according to the specific network environment. If there is no special requirement,
default values are recommended.
Pre-configuration Tasks
Before setting the parameters for controlling the SPT switchover, complete the following tasks:
l Configuring the unicast routing protocol to ensure that IP routes between nodes are
reachable
l 4.4 Configuring Basic PIM-SM Functions
Data Preparation
To set the parameters for controlling the SPT switchover, you need the following data.
No. Data
1 Threshold of the message rate for the RPT-to-
SPT switchover.
2 Group filtering policy and sequencing policy
for the RPT-to-SPT switchover
3 Interval for checking the threshold value of
multicast data rate before the RPT is switched
to the SPT
4.12.2 Setting the Interval for Checking the Transmission Rate of
Multicast Packets
Context
Do as follows on all the S9300s on the receiver side. By default, the RP and the DR on the
receiver side immediately perform the SPT switchover after receiving the first multicast packet.
Procedure
Step 1 Run:
system-view
