minimum-interval
to 60000 milliseconds.
incremental-interval
range of 10 to 60000 milliseconds.
Usage guidelines
Based on the LSDB, an OSPFv3 router uses SPF to calculate a shortest path tree with itself being
the root. OSPFv3 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
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.

no-summary
stub area. No AS-external-LSA, Inter-Area-Prefix-LSA, or other Inter-Area-Router-LSA is advertised
in the area. The area is a totally stub area.
Usage guidelines

To configure an area as a stub area, execute the
: Specifies the minimum OSPFv3 route calculation interval in the range of 10
: Specifies the incremental OSPFv3 route calculation interval in the
to restore the default.
: Enables the ABR to advertise only a default route in an Inter-Area-Prefix-LSA into the
configuration on an ABR, execute the
no-summary
: Enables the ABR to always advertise a default route
command on all routers attached to the area.
