maxage-lsa route-calculate-delay

Function

The maxage-lsa route-calculate-delay command configures the route calculation delay function to suppress frequent OSPF LSA flapping.

The undo maxage-lsa route-calculate-delay command disables the function.

By default, not enabled OSPF LSA routing delays the oscillation frequency calculation function.

Usage Guidelines

Usage Scenario

Frequent OSPF LSA flapping on the remote device may lead to route flapping on the local device, affecting services. To address this problem, run the maxage-lsa route-calculate-delay command to configure the local device to delay route calculation in the case of frequent OSPF LSA flapping, which suppresses route flapping locally.

Example

# Set the route calculation delay to suppress frequent OSPF LSA flapping to 200s.
