Default level
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.
Description
Use
spf timers
to configure the delay interval and hold interval for OSPFv3 SPF calculation.
Use
undo spf timers
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.
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.
