Configuring an Intelligent Timer for Generating LSAs
Context
Setting the millisecond-level interval for generating the same LSA speeds up network convergence. When a network becomes unstable, reduce the interval for generating the same LSA by using an intelligent timer.
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-originate-interval { 0 | intelligent-timer max-interval start-interval hold-interval [ other-type interval ] | other-type interval [ intelligent-timer max-interval start-interval hold-interval ] }
The interval for updating OSPFv3 LSAs by using an SPF intelligent timer is set.
By default, the maximum interval for updating LSAs is 5000 ms, the initial interval for updating LSAs is 500 ms, the hold interval for updating LSAs is 1000 ms.
- (Optional) Run lsa-originate-interval suppress-flapping suppress-interval
The maximum OSPFv3 LSA suppression period is configured.
If frequent OSPFv3 LSA flapping occurs, the larger value between lsa-originate-interval suppress-flapping and lsa-originate-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.
