Hi Dude, today i will write about how to show or print routing table in generally linux operating system. Show routes are very useful for system administrators or network engineers to troubleshoot networks.

Show route or routing table will give us the following information:

1. Accurate path of outgoing traffic after passing through the gateway.
2. Selection of the default gateway if it has more than 1 interface.

To display the kernel routing table, you can use any of the following methods:

Command route

This simple command using route. The command route is used to modify and check the existing routes. This will display the list of routes currently configured.

$ route -n
