In this practice demonstration, we explore Linux routing and learn how to: Use "route -n" to view the routing table Identify the default route (0.0.0.0) Determine which interface is being used for Internet traffic Use "ip route" to inspect modern Linux routing Use "ip route get 8.8.8.8" to see exactly which interface Linux will use Remove the existing default route Configure another interface as the default Internet route Understand the relationship between an interface, gateway, routing table, and the internet
