Abstract: Systems and methods are disclosed for monitoring routing data and issuing alarms for route anomalies detected based on the monitored routing data. Routing data, including Border Gateway Protocol (BGP) announcement and/or withdraw messages for a targeted prefix of an Autonomous System (AS), is collected and analyzed to detect route anomalies. The analysis may include a comparison of the BGP messages to internal routing data. An alarm is selectively output corresponding to the detected route anomalies. The detected route anomalies may be correlated with monitored network traffic data to classify the route anomalies, where the output of the alarm is based on the classification of the route anomalies.
