NOTE:
When network changes are not frequent, the minimum-interval is adopted. If network changes become
frequent, the SPF calculation interval is incremented by incremental-interval × 2 n-2 (n is the number of
calculation times) each time a calculation occurs until the maximum-interval is reached.
Specifying the LSA arrival interval
After receiving the same LSA as the previously received LSA within the LSA arrival interval, OSPF discards
the LSA.
Follow these steps to configure the LSA arrival interval:

Optional
1000 milliseconds by
default
NOTE:
The interval set with the lsa-arrival-interval command must be smaller than or equal to the interval set with
the lsa-generation-interval command.
Specifying the LSA generation interval
You can adjust the LSA generation interval to protect network resources and routers from being over
consumed by frequent network changes.
Follow these steps to configure the LSA generation interval:
To do… Use the command… Remarks

generation interval
lsa-generation-interval
maximum-interval [ initial-interval
[ incremental-interval ] ]
Optional
By default, the maximum interval is 5
seconds, the minimum interval is 0
milliseconds, and the incremental
interval is 5000 milliseconds.
NOTE:
When network changes are not frequent, LSAs are generated at the minimum-interval. If network changes
become frequent, the LSA generation interval is incremented by incremental-interval × 2 n-2 (n is the
number of generation times) each time a LSA generation occurs until the maximum-interval is reached.
