Parameter
seconds: Duration of one cycle in second of SPF calculation in the range from 0 to 120.
When the calculation duration time reaches or exceeds the set value, the calculation of
this time ends. If seconds is set to 0, it indicates that SPF calculation is not divided into
slices and it will operate until the end. By default, the value is 0.
Description
Using spf-slice-size command, you can configure the duration of one cycle when IS-IS
performs SPF route calculation. Using undo spf-slice-size command, you can restore
the default setting.
When there is a large number of routes in the routing table, this command can be used
to enable the SPF calculation in slices to prevent it from occupying the system
resources for a long time.
The user is recommended to use the command when the number of routes reaches
150,000 or 200,000 and the value of seconds is recommended as 1. In other cases, the
default setting should be used, that is, SPF runs to the end with no slice.
If the spf-delay-interval command is also configured, when SPF calculation is run, the
SPF calculation will be paused if any setting item is met.
For the related commands, see spf-delay-interval.
Example
# Set the SPF duration time to 1 second.
[Quidway-isis] spf-slice-size 1
