The Route Explorer/EIGRP Edition gives network engineers a real-time Layer 3 topology view of their networks, enabling them to more quickly and effectively diagnose and troubleshoot network problems. The product supports all four major routing protocols in common use within large enterprises and service providers: EIGRP, OSPF, IS-IS and BGP. It works by first discovering all EIGRP routers on the network and creating an end-to-end view of the topology. It then listens to the EIGRP protocol exchanges to learn when topology changes occur. By analyzing those exchanges and mapping the information onto the network topology, it can infer the root cause of any route change or other Layer 3 event to the most likely set of routers and links. Finally, the inference is validated and the source of the problem verified. Route Explorer places no significant load on the network infrastructure and scales to support the largest networks.--Packet Design
