[Sysname-ospfv3-1] router-id 10.1.1.3
Use spf-schedule-interval to set the OSPFv3 SPF calculation interval.
Use undo spf-schedule-interval to restore the default.
spf-schedule-interval maximum-interval [ minimum-interval [ incremental-interval ] ]
The maximum SPF calculation interval is 5 seconds, the minimum interval is 50 milliseconds, and the
incremental interval is 200 milliseconds.
Predefined user roles
maximum-interval: Specifies the maximum OSPFv3 route calculation interval in the range of 1 to 60
minimum-interval: Specifies the minimum OSPFv3 route calculation interval in the range of 10 to 60000
incremental-interval: Specifies the incremental OSPFv3 route calculation interval in the range of 10 to
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 bandwidth and router resources from being over-consumed due to
frequent topology changes.
When network changes are not frequent, OSPFv3 performs SPF calculations at the minimum-interval. If
network changes become frequent, the SPF calculation interval is incremented by the incremental-interval
each time a calculation happens until the maximum-interval is reached.
The minimum interval and the incremental interval cannot be greater than the maximum interval.
# Configure the maximum SPF calculation interval as 10 seconds, minimum interval as 500 milliseconds
and incremental interval as 300 milliseconds.
