Infrastructure Host 3 represents the kiosk station that needs to have its access limited to the local network. Host 4 represents another host in the Birmingham office Loopback 0 on the GAD router represents the Internet. Step 1 Basic Router Interconnection a. Interconnect the routers as shown in the diagram. Step 2 Basic Configuration a. The router may contain configurations from a previous use. For this reason erase the startup configuration and reload the router to remove any residual configurations. Using the information previously in the tables setup the router and host configurations and verify reachablilty by pinging all systems and routers from each system. b. To simulate the Internet add the following configuration to the GAD router. GAD config interface loopback0 GAD config-if address GAD config-if exit GAD config router rip GAD config-router network GAD config-if z Step 3 Establish Access
