Follow these steps to configure PIM-SM register-related parameters:
Enter system view
Enter PIM view
Configure a filtering rule
for register messages
Configure the device to
calculate the checksum
based on the entire
register messages
Configure the register
suppression timeout time
Configure the probe time
Note:
Typically, you need to configure the above-mentioned parameters on the receiver-side
DR and the RP only. Since both the DR and RP are elected, however, you should carry
out these configurations on the routers that may win the DR election and on the C-RPs
that may win RP elections.
6.3.7 Disabling RPT-to-SPT Switchover
Multicast traffic flows along an RPT to the receivers before an RPT-TO-SPT switchover
takes place. By default, the last-hop switch initiates an RPT-to-SPT switchover process
when it receives the first multicast packet from the RPT. You can disable RPT-to-SPT
switchover through the following configuration.
Follow these steps to disable RPT-to-SPT switchover:
