While this question seems extremely basic, discussing networking fundamentals is exactly what a company is looking for in a new hire. The Cisco interviewer expects you to respond with an explanation of the basic features of a router, its function, and how you use it. Keep your answer direct and to the point, using non-technical language. You should also be prepared for a follow-up question which the interviewer will use to dive deeper into the topic.

"A router is an intelligent switch which directs network traffic to and from nodes on the network. Efficient transmission of information is based on the routing protocol, which selects the best routes between any two nodes. Three typical types of routing protocol are Routing Information Protocol (RIP), Open Shortest Path First (OSPF), and Interior Gateway Protocol (IGP). I prefer OSPF, which is based on the Shortest Path First (SPF) algorithm; it calculates the shortest path to each node and is, therefore, the most efficient."
