Parameters
delay-interval: Interval in seconds between when OSPFv3 receives a topology change
and when it 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.
Description
Use the spf timers command to configure the delay interval and hold interval for
OSPFv3 SPF 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.
Examples
# Configure the delay interval and hold interval as 6 seconds for SPF calculation.
