4.6.1 Establishing the Configuration Task
Applicable Environment
On a PIM-SM network, the DR directly connected to multicast source S encapsulates the
received multicast data in a Register message and sends the Register message to an RP in unicast
mode. The RP then decapsulates the message, and forwards the multicast data to receivers along
the RPT.
After the SPT switchover on the RP is complete, the multicast data reaches the RP along the
SPT in multicast mode. The RP sends a Register-stop message to the DR on the multicast source
side. The DR then stops sending Register messages and enters the register suppression state.
During the register suppression, the DR sends null Register messages periodically to the RP,
notifying the RP that the multicast source remains in active state. After the register suppression
times out, the DR re-sends the Register message.
S9300s configured with default values can work normally. In the S9300, you can adjust related
parameters according to the specific network environment. If there is no special requirement,
default values are recommended.
