Abstract
Features are disclosed for managing routing rules stored by a routing device and used to manage network traffic in a network. A computing device can receive multiple routing rules corresponding to multiple routing devices in the network. The computing device can use a formal specification and a snapshot to generate a model of the network. The computing device may use the model in order to statically determine the set of possible paths without causing the transmission of data between a routing device and a destination. the computing device may compare the identified routing rules and the possible paths in order to determine excess routing rules. The computing device may remove the excess routing rules from the routing rules for each routing device such that each routing device routes subsequent network traffic based on the updated routing rules.
