These 3 complementary views highlight concrete, legible examples from the course presentation.
This screenshot displays a GNS3 network topology featuring an Ubuntu Linux node connected to a Cisco IOSv router and a NAT cloud, with terminal windows open to show the output of the ifconfig command.
This split-screen view shows a GNS3 topology alongside an Ubuntu terminal where the user checks the OS release version and encounters an error because the ifconfig command is not installed.
This desktop view demonstrates Linux network configuration by displaying the detailed output of ip addr and ip link commands within an Ubuntu terminal environment.
