spf-slice-size seconds
undo spf-slice-size
View
IS-IS view
Parameters
seconds: Duration time during SPF calculation, in milliseconds, ranging from 0 to 120.
A calculation is ended when the duration time is reached or exceeded. If the second
argument is set to 0, the SPF calculation will continue until it finishes. It is 0 by default.
Description
Use the spf-slice-size command to configure whether the SPF routing calculation is
fragmented and configure the duration time for each fragment.
Use the undo spf-slice-size command to resume the default configuration.
When there are too many routes in the routing table, you can use this command to
fragment the SPF calculation to avoid taking up the system resources for a long time.
You are not recommended to change the default configuration.
If the spf-delay-interval command is configured at the same time, the SPF calculation
will be paused if the SPF calculation matches any of the setting.
Related commands: spf-delay-interval.
Examples
# Set SPF duration time to one second.
