ROOT CAUSE ANALYSIS
Cause:
OSPF adjacencies went down between our equipment and the remote site vendor.
Resolution:
Vendor couldn’t narrow down to exactly what happened. All hardware and connection seem to be up. There was also no indication of failure on our end as a few other remote sites were still up and they were connected to the same equipment (router) in Harris Theater.
Prevention:
We leave the ticket open with the vendor for now and continue to monitor for any abnormal behaviors.
