Instructions – Follow instructions below –• Answer Template – The file ANSWERS_ …_TWO.docx, which is available onMoodle, must be used as the template for your answers. Write all of youranswers in this file, and upload1. the template document with answers and2. fully functional (mainly functional configuration from question 2 and4) ‘Assignment2.pkt’ which should work with Packet Tracer version7.1.• Workings and Calculations – You are recommended to show all your workings and steps inyour calculations. Although you may receive full marks if you give the correct answerwithout showing the calculations, you will receive zero (0) marks if you give the incorrectanswer without showing the calculations. If you show your workings and calculations, butarrive at an incorrect answer (e.g. due to a typo or small mistake), you may receive partialmarks. Hence, it is better that you show all your working and steps in your calculations.• Plagiarism – Please ensure that you write your answers in your own words to avoidpossible plagiarism and copyright violation. You can understand the PlagiarismProcedures by following the corresponding link in the CQUniversity Policies section ofthe unit profile.Question 1: (12 marks)BMTech is a medical service provider with three sub-branches located at Melbourne area. Themain branch and sub-branches have the network devices (such as computer, server, printer,etc.) 110, 40, 30 and 20 respectively. BMTech contracted with you to help them a proper IPaddress planning for the following new IP address space:IPv4 network: 192.168.10.0/24IPv6 network: 2001:DB80:ABCD:1000::/64Calculate the subnetworks and answer the following questions for all four of the subnetworks.Make sure you show detailed calculations to get full marks in this question.IPv4 network:
What is the subnet mask of the subnetwork?What is the first address and the last address of the subnetwork?

(2 marks)What is the first address and the last address of the subnetwork? (2 marks)Question 2: (1+2+2=5 marks)Open ‘Assignment2.pkt’ using Packet Tracer. All ports on all devices in the network arepre‐ configured with IP addresses. However, the routing protocol is not configured in therouters of the given network. Configure RIP version 2 routing protocol in each of thoserouters and test the connectivity of the network. Write CLI (Command Line Interface)commands you have used in both (HQ and Branch A) routers for RIP version 2 as youranswer and submit ‘your_student _ID.pkt’ file with functional routing. Include thescreenshot in your answers. Marking distribution ‐• Submitted fully functional ‘your_student_ID.pkt’ file with routing andincluded screenshot in the answer template(ANSWERS_ …_TWO.docx).(1 mark)• Correct routing commands in HQ router written in the answer template(ANSWERS_ …_TWO.docx).(2 marks)• Correct routing commands in Branch A router written in the answertemplate (ANSWERS_ …_TWO.docx).(2 marks)Question 3: (7 marks)In the given network of ‘Assignment2.pkt’, Branch A Router receives a packetwith destination address 188.8.131.52. Answer the following questions based onthe network.a) Construct the classful routing tables for Branch A router.(5 marks)b) Show the detailed process, with relevant calculations and conversions, of howthe packet is forwarded (classful) by Branch A Router.(2 marks)Question 4: (6 marks)At the moment, all the PCs in ‘Assignment2.pkt’ are configured with static IP addresses. Inthis question, you will configure DHCP in both (HQ and Branch A) routers for thecomputers belonging to the networks below:HQ router:• 184.108.40.206• 220.127.116.11Ass2‐COIT12206‐T1, 2020 Page: 2/ 3COIT12206 TCP/IP Principles & Protocols Assessment 2 Term 1, 2020Branch A router:• 192.168.2.0After you configure DHCP, remove the static IPs from relevant computers and chooseDHCP to obtain IP address. Finally, do not forget to test your network by sending apacket from one end to other.Write CLI (Command Line Interface) commands you have used in both (HQ andBranch A) routers for DHCP implementation as your answer and submit‘your_student_ID.pkt’ file with functional DHCP configuration. Include thescreenshot in your answers. Marking distribution ‐• Submitted fully functional ‘your_student_ID.pkt’ file with routing andincluded screenshot in the answer template. (1 mark)• Correct DHCP commands in HQ router written in the answer template. (2.5 marks)• Correct DHCP commands in Branch A router written in the answer template.(2.5 marks)– End –Ass2‐COIT12206‐T1, 2020 Page: 3 / 3
