On Linux and UNIX systems, information on how packets are to be forwarded is stored in a kernel structure called a routing table. You need to manipulate this table when configuring your computer to talk to other computers across a network. The routing table can be used for both static and dynamic routing.
What is meant by routing table?

What is a routing table and how does it work?
A routing table contains the information necessary to forward a packet along the best path toward its destination. Each packet contains information about its origin and destination.
