Command Reference
OSPFv3 Commands
Description
3.53 timers throttle spf
Use this command to configure, the delay for SPF calculation as well as the minimum and maximum
intervals between two SPF calculations after receiving the topology change information for OSPFv3
in the routing process configuration mode. Use the
no
form of this command to restore the default
setting.

Parameter
Description
Parameter
Description
spf-delay
Specifies an SPF calculation delay after the topology change
information is received.
The range is from 1 to 600000 in the unit of milliseconds.
spf-holdtime
Specifies a shortest interval between two SPF calculations.
The range is from 1 to 600000 in the unit of milliseconds.
spf-max-waittime
Specifies a longest interval between two SPF calculations.
The range is from 1 to 600000 in the unit of milliseconds.
Defaults
The default
spf-delay
is 1000.
spf-holdtime
is 5000 and
spf-max-waittime
is 10000.
Command
Mode
Routing process configuration mode.
Usage Guide
Spf-delay
refers to the delay from the topology change to the SPF calculation.
Spf-holdtime
refers to
the minimum interval between the first and the second SPF calculations. Then, the interval of the
consecutive SPF calculations is at least twice as the last interval till it reaches to
spf-max-waittime
. If
the interval between two SPF calculations has exceeded the required minimum value, the interval of
SPF calculation will re-start from
spf-holdtime
.
Smaller
spf-delay
and
spf-holdtime
value can make the topology convergence faster. Greater
spf-max-waittime
value can reduce the SPF calculations. Those configuration are flexible according
to the actual stability of the network topology.
Compared with the timers spf command, this command is more flexible. It not only speeds up the
SPF convergence calculation, but also reduces the system resources consumption of SPF calculation
as the topology changes continuously. Therefore, the timers throttle spf command is recommended.
The spf-holdtime cannot be smaller than spf-delay, or the spf-holdtime will be set to be equal
to spf-delay;
The spf-max-waitime cannot be smaller than spf-holdtime, or the spf-max-waittime will be set
to be equal to spf-holdtime automatically;
The configuration of the timers spf command and of the timers throttle spf command
are
