Step
3.
Specify the SPF
calculation interval.

Specifying the LSA arrival interval

If OSPF receives an LSA that has the same LSA type, LS ID, and router ID as the previously received LSA
within the LSA arrival interval, OSPF discards the LSA to save bandwidth and route resources.
To configure the LSA arrival interval:
Step
1.
Enter system view.
2.
Enter OSPF view.
3.
Configure the LSA arrival
interval.

Specifying the LSA generation interval

Adjust the LSA generation interval to protect network resources and routers from being overwhelmed by
LSAs at the time of frequent network changes.
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
the number of generation times) each time a LSA generation occurs until the maximum-interval is
reached.
To configure the LSA generation interval:
Step
1.
Enter system view.
2.
Enter OSPF view.
