starts SPF calculation. in the range 1 to 65535. 

hold-interval: Hold interval in seconds between two consecutive SPF calculations, in the range 1 to 

65535.

calculation.  

Use the undo spf timers command to restore the default.  

The delay interval and hold interval default to 5s and 10s. 

An OSPFv3 router works out a shortest path tree with itself as root based on the LSDB, and decides on 

the next hop to a destination network according the tree. Adjusting the SPF calculation interval can 

restrain bandwidth and router resource from over consumption due to frequent network changes.  

# Configure the delay interval and hold interval as 6 seconds for SPF calculation.
