Disabling Spt Switchover - HP A5500 SI Switch Series 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.
Follow these steps to configure register-related parameters:
To do...
Enter system view
Enter IPv6 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
time
Configure the register probe time

Disabling SPT switchover

If an A5500 EI switch acts as an RP or the receiver-side DR, it initiates an STP switchover process by
default upon receiving the first IPv6 multicast packet along the RPT. You can disable the switchover from
RPT to SPT.
Follow these steps to configure SPT switchover:
To do...
Enter system view
Enter IPv6 PIM view
Disable the SPT switchover
CAUTION:
For an A5500-EI switch, once an IPv6 multicast forwarding entry is created, subsequent IPv6 multicast
data will not be encapsulated in register messages before being forwarded even if a register outgoing
interface is available. Therefore, to avoid forwarding failure, do not use the spt-switch-threshold
infinity command on a switch that might become an RP—namely, a static RP or a C-RP.
Use the command...
system-view
pim ipv6
register-policy acl6-number
register-whole-checksum
register-suppression-timeout
interval
probe-interval interval
Use the command...
system-view
pim ipv6
spt-switch-threshold infinity [
group-policy acl6-number [ order
order-value ] ]
