    180 In this experiment you will learn how to set up static routing with the <em>route</em> command.
    181 
    182 In this exercise, you will setup the routing as indicated in the figure; i.e. packets from A sent to IP address 192.168.2.12 on node C should be routed via node B. In order to create this routing behavior you will need to modify the routing tables in your nodes using the linux

     169In this experiment you will learn how to set up static routing with the `route` command.
