Hi @Mohammed_Yasin ,

 

It looks like your OSPF adjacency flapped.

 

As to why this happened you'll need to do further debugging.

The timeframe allows you to narrow down and check other logs for related events.  Also check the traffic log during the timeframe when this occured.

 

Get the TSF and have it analysed by support.

 

Cheers,

-Kiwi.
