Command Reference OSPFv3 Commands
Use this command to set the delay and interval for the OSPFv3 to calculate SPF after receiving the
topology change. Use the no format of this command to restore the default setting.
timers spf delay holdtime
Defines the waiting time for the SPF calculation, which ranges from 0
to 2147483647 seconds. After receiving the topology change
information, the OSPF routing process has to waiting for a given
period before making the SPF calculation.
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.
There are two default situations: 1. The versions earlier than RGOS 10.4 do not support the
command timers throttle spf. The system default is timers spf 5 10. 2. The RGOS 10.4 and the later
versions do support the command timers throttle spf, where timer spf takes no effect by default.
The delay for SPF calculation is subject to the default setting of the command timers throttle spf.
Refer to the description of the command.
Routing process configuration mode
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.
The following example sets the delay and holdtime of the OSPFv3 to 3 seconds and 9 seconds
respectively.
Ruijie(config)# ipv6 router ospf 20
Ruijie(config-router)# timers spf 3 9
Restarts part of the function of the OSPFv3.
