Part 2: Observe a Network Failover with Redundant Switches Background / Scenario In this activity, you will observe the successful failover of the Metropolis network utilizing multiple routers to provide default gateway redundancy. Afterwards across the world, you will observe the successful network failover of the Gotham network utilizing multiple switches to provide redundant network pathways. The IP addressing, network configuration, and service configurations are already complete. You will use the client devices in the differing geographic regions to evaluate the pathways before and after successful network failover. Screenshots (Output) For screenshots (snips) make sure to include enough to determine proper source and/or target devices. This could be via including the name of the PC/Device, the hostname of the networking device (Router or switch) or ipconfig output Refer to the PDF in Blackboard Menu: Labs > “Screenshot Capture for Labs and Assignments” > “Labs – Screenshots” > IST_110_Lab_PT_Screen_Outputs.pdf GTC - CPT Dept Page 1 of 10 IST 110 Lab

GTC IST-110 PT Lab: Router and Switch Redundancy Part 1: Observe a Network Failover with Redundant Routers. Step 1: Access the command prompt on Phil’s computer. a. Click the Metropolis Bank HQ site and then click the laptop Phil. b. Click the Desktop tab and then click Command Prompt Step 2: Trace the pathway to the External Web server. a. Ping the External Web server on the Internet by entering ping 209.165.201.10 in the command prompt. b. Trace the pathway to the External Web server on the Internet by entering tracert 209.165.201.10 in the command prompt. Screenshot (below): Phil’s laptop > ping and tracert (single snip) Note: show pertinent output ~ See Screenshots (Output) section GTC - CPT Dept Page 2 of 10 IST 110 Lab

GTC IST-110 PT Lab: Router and Switch Redundancy c. Each IP address shown in the output of the tracert command is a network device that network traffic is crossing. The first address of the tracert output is the default gateway (exit point) of the network. d. Comparing the output of the tracert command to the Addressing Table at the beginning of this lab, which router is operating as the current default gateway of the network? (List router name and IP address) R1, 10.44.1.2 Step 3: Cause a network failover. a. Within the Metropolis Bank HQ site, click the switch HQ_S1. b. Click on the CLI tab (Command Line Interface tab) and hit the Enter key at least once to display the proper CLI prompt: c. Disable the uplink port Gig0/2 using the following commands: To copy into a Packet Tracer command prompt , use the RIGHT CLICK and PASTE event Do not use keyboard shortcuts Note: Copy the text EXACTLY as you see it here: enable configure terminal interface GigabitEthernet0/2 shutdown d. Once you have Pasted the code (above) hit the ENTER key at least once to have the following output show: GTC - CPT Dept Page 3 of 10 IST 110 Lab

Click the Desktop tab and then click Command Prompt. c. Ping the External Web server on the Internet by entering ping 209.165.201.10 in the command prompt. d. Trace the pathway to the External Web server on the Internet by entering tracert 209.165.201.10 in the command prompt.
