“Question 3 (30 marks) This question allows you to demonstrate your ability to configure and test a network of routers using Ciscos Packet Tracer simulator. The Packet Tracer file for this question T216_13B_TMA02_Q3.pka will be found here. To answer the question open Packet Tracer and load this file. Configure your network as shown in Figure 1 using Command Line Interface (CLI) instructions. Your configuration should be as complete as possible. Include: . hostnames as given below . enable secret password class . console password cisco . 5 vty lines password cisco . correctly configured interfaces using DCE clock rates of 56000 bps as required . RIP routing protocol v1 . message of the day banner with the message: Unauthorized access prohibited! There is no requirement to configure any switches or PCs as they have been preconfigured for you. For this question all you need to configure are the three routers in the network shown in Figure 1. The Packet Tracer configuration function has been disabled so you will have to configure the routers through the CLI as if you were accessing them via the console interface or via telnet. No link exists between Router2 and Router3, so the associated interfaces should not be configured at this time. Q3 Tasks The routers at your company’s network were interconnected as shown in Figure 1 on the previous page but have not yet been configured. It is your role to configure the routers using the configuration list shown above and addressing table shown in Table 1. Then test the network to ensure it all works. The switches and PCs have already been configured in the Packet Tracer file associated with this question. The secret password and the banner message do not contribute to this score, neither do shutdown commands. (a) Copy and paste into your answer document the configuration for R2 as given when you type the show running-configuration command. Highlight the text you want to copy and press the copy button to save to the clipboard. You can then paste this text into your answer document. Figure 1 Network (indicators have been turned off for clarity) Add a one line descriptive comment on each command or group of commands you enter stating what the commands are doing. Comments are preceded by an exclamation mark. Also you should edit out unnecessary lines (such a blank lines and additional compilation text) leaving only the lines showing your configuration and comments. You will be penalised by up to two marks if you fail to do this editing. (15 marks) (b) Insert a screenshot into your answer document to show the results of typing a command on R1 to display the routing table. Explain, in a sentence or two, each line of the output and how it shows that this router is learning about the network. Pay particular attention to the metrics. Marks will be lost if an inappropriate command is chosen to display the routing table or if a screenshot is not given. You will be penalised 1 mark if you fail to show a screenshot. (3 marks) (c) Insert a screenshot into your answer document to show the results of typing a command on R3 to display a single-line IP status for each interface. Describe, in one or two sentences, what this information tells you about each of the interfaces on this router. Marks will be lost if an inappropriate command is chosen or if a screenshot is not given. You will be penalised by 1 mark if you fail to show a screenshot. (2 marks) (d) Describe briefly how you tested your network to ensure you have connectivity for each PC on the network. Give a screenshot from PC2 showing that this PC can communicate with the other two PCs. These PCs and switches have been configured for you and will work if you have configured the routers correctly. You will be penalised by 2 marks if you fail to show an appropriate screenshot in your answer. (5 marks) (e) Save your Packet Tracer fil”
