Parameters
maximum-interval
: Specifies the maximum OSPF SPF calculation interval in the range of 1 to
60 seconds.
minimum-interval

incremental-interval
: Specifies the incremental OSPF SPF calculation interval in the range
of 10 to 60000 milliseconds.
Usage guidelines
Based on the LSDB, an OSPF router uses SPF to calculate a shortest path tree with itself as the root.
OSPF uses the shortest path tree to determine the next hop to a destination. By adjusting the SPF
calculation interval, you can prevent overconsumption of bandwidth and router resources due to
frequent topology changes.
For a stable network, the minimum interval is used. If network changes become frequent, the SPF
calculation interval is incremented by the incremental interval × 2
n-2
for each calculation until the
maximum interval is reached. The value
n
is the number of calculation times.
The minimum interval and the incremental interval cannot be greater than the maximum interval.
Examples
# Set the maximum SPF calculation interval to 10 seconds, minimum interval to 500 milliseconds,
and incremental interval to 300 milliseconds.
