| As you know, having the topology of a network is extremely useful. It allows a network administrator to know exactly what equipment he or she has in what area (for bandwidth needs), how many devices are on the network and the physical layout of the network. In this lab you will need to figure out what a topology looks like based on the information you can gather while navigating through the network using IOS commands. Through the use of show commands, you should be able to see which interfaces are up (using show interface), what devices the router is connected to (using show CDP neighbors) and how the user can get there (using show protocols). With the information received from the show commands, you should be able to remotely access the neighboring routers (using telnet) and through the use of troubleshooting commands (such as ping and trace) you should be able to see which devices are connected. Your final goal is to construct a logical topology drawing of the network by making use of all the above commands without referring to any diagrams ahead of time.
