Configuring Switchover To Spt - HP MSR ASM Configuration Manual

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 source-side DRs.
To configure register-related parameters:
Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance 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 multicast packets
and thus trigger a switchover to SPT.
Perform the following configuration on routers that might become receiver-side DRs and on C-RP routers.
To configure SPT switchover:
Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Configure the criteria for
triggering a switchover to SPT.
4. Configure the interval of
checking the traffic rate
threshold before initiating a
switchover to SPT.

Optional.
By default, the device switches to the
SPT immediately after it receives the
first multicast packet.
If the multicast source is learned
through MSDP, the device will switch
to the SPT immediately after it
receives the first multicast packet, no
matter how big the traffic rate
threshold is set.
Optional.
15 seconds by default.
