Configuring Switchover To Spt - HP MSR2003 Configuration Manual

The register-stop timer is set to a random value chosen uniformly from (0.5 × register_suppression_time
minus register_probe_time) to (1.5 × register_suppression_time minus register_probe_time). The
register_probe_time is fixed to 5 seconds.
On all C-RP routers, configure a filtering rule for register messages and configure the device to calculate
the checksum based on the entire register messages.
On all routers that might become the source-side DR, configure the register suppression time.
To configure multicast source registration:
Step
1. Enter system view.
2. Enter PIM view.
3. Configure a filtering rule for
register messages.
4. Configure
calculate the checksum based
on the entire register message.
5. Configure
suppression time.

Configuring switchover to SPT

CAUTION:
If the device is an RP, disabling switchover to SPT might cause multicast traffic forwarding failures on the
source-side DR. When disabling switchover to SPT, be sure you fully understand its impact on your
network.
Both the receiver-side DR and RP can monitor the traffic rate of passing-by multicast packets and thus
trigger a switchover from RPT to SPT. The monitor function is not available on switches.
To configure the switchover to SPT:
Step
1. Enter system view.
2. Enter PIM view.
3. Configure
triggering a switchover to SPT.
NOTE:
If the multicast source information is learned through MSDP, the device switches to SPT immediately after
it receives the first multicast packet, regardless of the traffic rate threshold.
