| Lab Activity
| You and your group are administrators of a LAN. Due to the rapid expansion of this company, you need to link the headquarters (your group's router) to the rest of network. You must link up the networks via the serial ports, which means that your group is responsible for only your router's connections. Before starting this lab, the Lab Assistant or the Instructor should erase the running configuration and the startup configuration for Lab-A only and make sure that the rest of the routers are configured with the standard lab setup. You will also need to verify your workstation IP configuration so you can test the connectivity between workstations and routers.
