  • Validating a routing function
    Patent number: 9742660
    Abstract: Certain examples described herein provide a system and method for validating a routing function for a network device. In one example, a network device has a run-time policy engine, wherein the run-time policy engine implements a routing configuration file and the routing configuration file defines a routing function for network traffic. A file editor is also provided that loads the routing configuration file. The file editor has an editor policy engine that duplicates a functionality of the run-time policy engine. In one example, the routing configuration file has at least one validation portion that has one or more route statements with definitions indicative of expected routing function behavior. The file editor parses the routing configuration file by implementing the routing configuration file using the editor policy engine.
