Configuring a Route Calculation Delay to Suppress Frequent LSA Flapping
Context
Frequent OSPFv3 LSA flapping may lead to route flapping, adversely affecting services. To address this problem, run the maxage-lsa route-calculate-delay command to configure the device to delay route calculation when it receives a MaxAge Router LSA, which suppresses the frequent OSPFv3 LSA flapping that may occur.
Procedure
- Run system-view
The system view is displayed.
- Run ospfv3 [ process-id ]
The OSPFv3 view is displayed.
- Run maxage-lsa route-calculate-delay delay-interval
A route calculation delay is configured and will be triggered when the device receives a MaxAge Router LSA.
By default, the delay is 20s.
- Run commit
The configuration is committed.
