Simple Static Routing Experiment
Overview
In this experiment you will learn how to set up static routing with the route
command. We will use the following network topology for this experiment:

Set Up
For this experiment you need a GENI account, ssh credentials, and the class VirtualBox
image. You also need to set up the experiment with Flukes. If you do not already have this set up, go to the setup page for instructions on how to set up your account.
Experiment
The goal of your final experiment is to setup the routing as indicated in Figure 1. You might want to review the slides on IPv4 addressing and routing (also chapter 4.4 in the book)

After you have set up the routing correctly, packets from A send to IP address 192.168.2.12 on node C should be routed via node B. Packets from A send to IP address 192.168.3.12 on node C should be directly forwarded to C. You can verify this by performing a traceroute to the respective IP addresses of node C from node A. Since we’re not using a routing algorithm but set the route statically, we will make use of the “route” command. The following link gives you an introduction on how to use the command:
Remember that you can use “ifconfig” to determine which Ethernet interface (e.g., eth0) is bound to what IP address at each of the nodes.
To enable forwarding of packets on node B you have to execute the following command:
echo 1 > /proc/sys/net/ipv4/ip_forward
To demonstrate that you have set up the routing correctly you have to submit a screenshot from node A that shows traceroutes for both IP addresses of node C. Note: You should document the steps you perform to set up the static routes since all configurations will be lost when your slice is deleted. A new slice will always be in its initial state with NO routing set up!
