Setting The Lsa Arrival Interval; Setting The Lsa Generation Interval - HP FlexFabric 12900E Series Configuration Manual

calculation interval.

Setting 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 set the LSA arrival interval:
Step
1. Enter system view.
2. Enter OSPF view.
3. Set the LSA arrival interval.

Setting 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.
For a stable network, the minimum interval is used. If network changes become frequent, the LSA
generation interval is incremented by the incremental interval × 2
maximum interval is reached. The value n is the number of generation times.
To set the LSA generation interval:
Step
1. Enter system view.
2. Enter OSPF view.
3. Set
generation interval.
