OSPF view 

2: System level 

maximum-interval: Maximum OSPF route calculation interval in seconds, in the range 1 to 60. 

minimum-interval: Minimum OSPF route calculation interval in milliseconds, in the range 10 to 60000, 

which defaults to 0. 

incremental-interval: Incremental value in milliseconds, in the range 10 to 60000, which defaults to 

5000.  

Use the spf-schedule-interval command to set the OSPF SPF calculation interval.  

Use the undo spf-schedule-interval command to restore the default. 

The interval defaults to 5 seconds. 

Based on its LSDB, an OSPF router calculates the shortest path tree with itself being the root, and uses 

it to determine the next hop to a destination. Through adjusting the SPF calculation interval, you can 

protect bandwidth and router resources from being over-consumed due to frequent network changes.  

With this command configured, when network changes are not frequent, SPF calculation applies at the 

minimum-interval. If network changes become frequent, the SPF calculation interval is incremented by 

the incremental-interval each time a calculation happens, up to the maximum-interval. 

# Configure the SPF calculation maximum interval as 10 seconds, minimum interval as 500 

milliseconds and incremental interval as 200 milliseconds.
