Routers connect computer networks and use routing tables to determine the best path for forwarding packets between networks. They support process and fast switching to process packets, with fast switching being more efficient. Default gateways allow devices to communicate with other networks when a specific route is unknown. Router interfaces must meet criteria like having an IP address to be available. Loopback interfaces allow routers to test themselves without affecting live traffic. Routing tables contain network addresses, interfaces, and metrics to inform forwarding decisions.

- 1. BAIT2164 COMPUTER NETWORKS 1 Tutorial 5 1. Discuss the purpose of routing and the functions of a router. 2. Routers support three packet-forwarding mechanisms. Differentiate process switching and fast switching methods. 3. What is the function of default gateways? 4. What are the criteria to make a router interface available? 5. What is the purpose of configuring loopback interface? 6. Describe the information stored in the routing table in a router. 7. Illustrate how routers switch packets between networks based on the topology in Figure 1. Figure 1 8. Briefly explain the packet forwarding decision process on a router.
