Route manipulates the kernel’s IP routing tables. Its primary use is to set up static routes to specific hosts or networks via an interface after it has been configured with the ifconfig(8) program.
When the add or del options are used, route modifies the routing tables. Without these options, route displays the current contents of the routing tables.
In this article we will show you how to use the route command to add/delete default gateway, add/delete a route with a temporary way, it means that the changes will be lost if the system is shutdown or reboot.
