As a network administrator, it is important to know the routing table in depth when troubleshooting network issues. Understanding the structure and lookup process of the routing table will help you diagnose routing table issue. For example, you might encounter a situation in which the routing table has all of the routes you expect to see, but packets are not being forwarded as expected. Knowing how to look through the process of a destination IP address for a packet will help you determine whether the packet is being forwarded as expected, if it’s being sent elsewhere, why it’s being sent elsewhere or whether the packet has been discarded. The best explanation in a layman’s language that everyone will understand.
