With the Routing Log Viewer tool, you can load two routing table logs and then view the differences between them. This approach can help you discover changes that have occurred in the routing topology between different sets of logs. The log with the most recent timestamp is the log labeled with the change status Added, Removed, or Modified. As long as the timestamp is different, it's not important which log you open first. If the timestamps are the same, the comparison is performed from the perspective of the first log opened.
