Usage Guidelines

Usage Scenario

The display ospf statistics updated-lsa command displays the frequent updates of LSAs, facilitating the location of the cause for a routing flapping.

If the history parameter is not configured, the display ospf statistics updated-lsa command only displays the updates of LSAs within the latest hour.
If the history parameter is configured, the display ospf statistics updated-lsa command displays the change history of LSAs within the last 24 hours.

Precautions

If you run the reset ospf command to restart the OSPF process, the real-time and historical statistics on the process will be cleared.
The display ospf statistics updated-lsa command is used only to display the frequent updates of LSAs. The updated LSAs are compared with the LSAs in the local LSDB, and those with the age greater than 900 will not be displayed except those with the age of 3600.

Example

# Display the LSA updates within the last one hour.
