Configuring Switchover To Spt - HP MSR ASM Configuration Manual

The register-stop timer is set to a random value chosen uniformly from the interval (0.5 times
register_suppression_time, 1.5 times register_suppression_time) minus register_probe_time.
Configure a filtering rule for register messages on all C-RP routers and configure them to calculate the
checksum based on the entire register messages. Configure the register suppression time and the register
probe time on all routers that might become IPv6 source-side DRs.
To configure register-related parameters:
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure a filtering rule for
register messages.
4. Configure the device to
calculate the checksum based
on the entire register
messages.
5. Configure the register
suppression time.
6. Configure the register probe
time.

Configuring switchover to SPT

Both the receiver-side DR and the RP can periodically check the traffic rate of passing-by IPv6 multicast
packets (this function is not available with switches) and thus trigger a switchover from RPT to SPT.
Perform the following configuration on routers that might become receiver-side DRs and on C-RP routers.
To configure switchover to SPT:
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure the criteria for
triggering a switchover to SPT.
4. Configure the interval of
checking the IPv6 multicast
traffic rate threshold before
triggering an SPT switchover.

By default, the device switches to
the SPT immediately after it
receives the first IPv6 multicast
packet from the RPT.
The traffic-rate argument is not
supported on a switch.
