2: System level
Parameters
delay-interval: Interval in seconds between when OSPFv3 receives a topology change and when it starts
SPF calculation, in the range of 0 to 65535.
hold-interval: Hold interval in seconds between two consecutive SPF calculations, in the range of 0 to
65535.
Usage guidelines
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.
Setting both the delay-interval and hold-interval to 0 triggers an SPF calculation at once, improving the
network convergence speed.
Examples
# Configure the delay interval and hold interval as 6 seconds for SPF calculation.
