Specifying Spf Calculation Interval; Specifying The Lsa Arrival Interval - HP 6125XLG Configuration Manual

To specify the LSA transmission delay on an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Specify the LSA transmission
delay.

Specifying SPF calculation interval

LSDB changes result in SPF calculations. When the topology changes frequently, a large amount of
network and router resources are occupied by SPF calculation. You can adjust the SPF calculation interval
to reduce the impact.
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
calculation times) each time a calculation occurs until the maximum-interval is reached.
To configure the SPF calculation interval:
Step
1. Enter system view.
2. Enter OSPF view.
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.
