Setting the Interval for Receiving LSAs
Context
When a network is unstable, control the minimum interval for receiving the same LSA update. To prevent unnecessary LSA updates caused by network changes, by default, an intelligent timer is enabled. The interval for receiving LSAs is expressed in milliseconds. The maximum interval for updating LSAs is 1000 milliseconds (ms), the initial interval is 500 ms, and the Holdtime interval is 500 ms.
Do as follows on the switch that runs OSPFv3.
Procedure
- Run system-view
The system view is displayed.
- Run ospfv3 [ process-id ]
The OSPFv3 view is displayed.
- Run lsa-arrival-interval { interval | intelligent-timer max-interval start-interval hold-interval }
The interval for receiving LSAs is set.
- (Optional) Run lsa-arrival-interval suppress-flapping suppress-interval
The maximum OSPFv3 LSA suppression period is configured.
If frequent OSPFv3 LSA flapping occurs, the larger value between lsa-arrival-interval suppress-flapping and lsa-arrival-interval is used to suppress LSA flapping.
By default, if the device receives an LSA, it delays route calculation for 10s.
- Run commit
The configuration is committed.
