Project $12-3$

In this hands$-$on project, you view and configure the route table on your Fedora Linux virtual machine as well as view and test your routing configuration.

$1.$ On your Fedora Linux virtual machine, switch to a command$-$line terminal $($tty$5)$ by pressing Ctrl$+$Alt$+$F$5$ and log in to the terminal using the user name of root and the password of LINUXrocks!.

$2.$ At the command prompt, type route $-$n and press Enter. What entries are listed? What does each entry represent? What IPv$4$ address is listed as your default gateway? What other commands can be used to list the route table?

$3.$ At the command prompt, type ip route add $1\mathrm{.}0\mathrm{.}0\mathrm{.}0/8$ via gwIP and press Enter, where $\backslash (\backslash$operatorname$\{$gwIP$\}\backslash )$ is the IPv$4$ address of your default gateway.

$4.$ At the command prompt, type route $-$n and press Enter. Is the route added in Step $3$ visible? Will this route interfere with traffic that is sent to the $1\mathrm{.}0\mathrm{.}0\mathrm{.}0$ network? Explain.

$5.$ At the command prompt, type traceroute www$.$ kernel.org and press Enter. How many routers are used to pass your packet to the ftp$.$kernel.org computer?

$6.$ At the command prompt, type tracepath www$.$ kernel.org and press Enter. Is the same path taken? If not, explain why.
