information, the OSPF routing process has to waiting for a given
period before making the SPF calculation.
spf-holdtime
Defines the interval between two SPF calculations, which ranges
from 0 to 2147483647 seconds. If the interval has not passed even if
the waiting time has elapsed, no SPF calculation can be made yet.
Defaults

. The system default is timers spf 5 10. 2. The RGOS 10.4 and the later

Usage Guide
The smaller the
spf-delay
and
spf-holdtime
, the shorter time the OSPF takes to adapt to the topology
change, but the more CPU time will be used of the router.
The
timer spf
configuration and the
timers throttle spf
configuration will overwrite each other.
Configuration
Examples
The following example sets the delay and holdtime of the OSPFv3 to 3 seconds and 9 seconds
respectively.
