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^n-² for each generation until the maximum interval is reached. The value n is the number of generation times.

To set the LSA generation interval:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enter OSPF view.	ospf [ process-id \| router-id router-id \| vpn-instance vpn-instance-name ] *	N/A
3. Set the LSA generation interval.	lsa-generation-interval maximum-interval [ minimum-interval [ incremental-interval ] ]	By default: The maximum interval is 5 seconds. The minimum interval is 50 milliseconds. The incremental interval is 200 milliseconds.
