be specified as 0.
@end deffn
@deffn {OSPF6 Command} {timers throttle spf @var{delay} @var{initial-holdtime} @var{max-holdtime}} {}
@deffnx {OSPF6 Command} {no timers throttle spf} {}
This command sets the initial @var{delay}, the @var{initial-holdtime}
and the @var{maximum-holdtime} between when SPF is calculated and the
event which triggered the calculation. The times are specified in
milliseconds and must be in the range of 0 to 600000 milliseconds.
The @var{delay} specifies the minimum amount of time to delay SPF
calculation (hence it affects how long SPF calculation is delayed after
an event which occurs outside of the holdtime of any previous SPF
calculation, and also serves as a minimum holdtime).
Consecutive SPF calculations will always be seperated by at least
'hold-time' milliseconds. The hold-time is adaptive and initially is
set to the @var{initial-holdtime} configured with the above command.
Events which occur within the holdtime of the previous SPF calculation
will cause the holdtime to be increased by @var{initial-holdtime}, bounded
by the @var{maximum-holdtime} configured with this command. If the adaptive
hold-time elapses without any SPF-triggering event occuring then
the current holdtime is reset to the @var{initial-holdtime}.
@example
@group
router ospf6
timers throttle spf 200 400 10000
@end group
@end example
In this example, the @var{delay} is set to 200ms, the @var{initial
holdtime} is set to 400ms and the @var{maximum holdtime} to 10s. Hence
there will always be at least 200ms between an event which requires SPF
calculation and the actual SPF calculation. Further consecutive SPF
calculations will always be seperated by between 400ms to 10s, the
hold-time increasing by 400ms each time an SPF-triggering event occurs
within the hold-time of the previous SPF calculation.
