Question: TMA 02 Question 3 (30 marks)

This question allows you to demonstrate your ability to configure and test a network of routers using Cisco’s 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 file as _T216_13B_TMA02_Q3.pka where is your Open University Personal Identifier code (in the form A1234567). You can find this code on your StudentHome home page. Zip up a copy of this file along with your answer document and send to your tutor using the online TMA/EMA service. Details of how to do this can be found from the Help section of your StudentHome.
(5 marks)

Question 4 (25 marks)
All parts of this question are about IP addresses. You can only gain full marks if you show your workings and/or explanations as appropriate. Giving just a numeric answer will not be sufficient to gain full marks. Note: subnet 0 should be used as the first usable subnet in all parts of
this question. Contact your tutor if you are unsure what this means.

(a) The following questions relate to a 172.16.0.0/12 network IPv4 address.
(i) Which portion of the network IP address 172.16.0.0/12 is the network, which part is the host and which gives the subnet mask? How have you been able to identify these parts, and how many networks and hosts can this network address support?
(4 marks)

(ii) What subnet mask should be applied to the network IP address 172.16.0.0/16 to give at least 100 useable hosts per subnet with the maximum possible number of subnets? (2 marks)

(b) The class C network IP address allocated to a network administrator is 192.168.150.0/28.
(i) How many possible subnets are there? (2 marks)

(ii) How many hosts and how many usable hosts are there in each subnet? (4 marks)

(iii) What is the network address of the second subnet? (2 marks)

(iv) What is the broadcast address of the sixth subnet? (2 marks)

(v) What is the address of the first useable host in the eleventh subnet? (2 marks)

(c) The IP addresses used in this question so far are part of a special set of private IP address blocks used on computer networks.

(i) Write down the missing private address (block) and its subnet mask.

(ii) Describe how the use of private IP addresses differs from the public IP addresses found on the internet.

(iii) What techniques are employed to ensure hosts using these addresses can still access the internet?
Note that this question refers to private address blocks listed in RFC 1918 and should not include any other reserved addresses.
(5 marks)

Question 5 (20 marks)
The following three listings were taken from a network simulated on Packet Tracer. The show ip route command was executed on each of the three routers in the network. For clarity, unnecessary output has been omitted. The routers used were Cisco 1841, each with the WIC-2T 2 port asynchronous/synchronous serial network module fitted. (The same routers and interfaces as used in Question 3). Assume FastEthernet interfaces have been assigned the lowest usable address on the networks to which they are directly connected.

Q5 Tasks
Use the information in the three listings above to answer the following questions (a–d):

(a) Provide an addressing table showing which device interfaces have been assigned to which IP addresses and subnet masks.
(5 marks)

(b) Derive the topology diagram of your network based on your interpretation of the listings shown on the previous page. You need only show the three routers and their interface connections – there is no need to show any other devices. You may provide an annotated screenshot from Packet Tracer or use any drawing aid you choose (a scanned drawing will be acceptable) but the correct symbols must be used for devices and interconnects. You should include the devices, interconnecting cables, interface identification and network addresses.
(4 marks)

(c) Provide a configuration listing for the Campus2 router. To keep your listing to a manageable length, only show the configuration for this router and do not include any extraneous output or blank lines. (6 marks)

(d) Describe briefly how you went about using the ‘show IP route’ command outputs to identify the topology of an unknown network. Why do you think this output is more useful than say looking at the running configuration files of each router? Your answer should not exceed 300 words – one mark will be deducted for answers over 300 words.
