The routing table is the way in which local hosts help network traffic determine where to go. It contains a set of road signs that send traffic to a specific interface and to a specific next location on its journey.

If you run any virtual machine or container, they will get their own IP address and subnet, which may complicate these routing tables, but there are usually two instructions in a single host. For local traffic, it is sent to the local Ethernet, and the network switch will find out (using a protocol called ARP) which host has the destination IP address and where to send the traffic. For traffic to the Internet, send it to the local gateway node, which will better understand how to reach the destination.

In the above case, the first line represents the external gateway of external traffic, the second line represents local traffic, and the third line represents the virtual bridge of the virtual machine running on the host, but the link is not currently active.
