Usage Guidelines

Usage Scenario

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.

Example

# Configure the device to delay route calculation for 200s when the device receives a MaxAge Router LSA.
