Packet Design introduced a route analysis system for Cisco’s Enhanced Interior Gateway Routing Protocol (EIGRP), which is used on more than half of all enterprise networks. The system gives network engineers a real-time layer 3 topology view of their networks.
Route Explorer/EIGRP Edition 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.
In addition to the EIGRP capability, Packet Design’s Route Explorer supports OSPF (Open Shortest Path First), IS-IS (Intermediate System-Intermediate System) and BGP (Border Gateway Protocol). http://www.packetdesign.com
