ASSIGNMENT-1 (20%)LOCAL AREA NETWORK TECHNOLOGIESObjective:By completing this assignment, students will be demonstrating their knowledge and skills learnt from session 1-5 that include:o IP address planning o Local Area Network technologieso Implement and configure Local Area Network of medium complexity in Cisco Packet TracerScenarioThe National Library of Australia recently restructruing and needs to develop a new local area network to meet business requirements. You are hired by the National Library to design and build the network.The initial phase involves design and development of a network for a number of buildings as shown in the below map.The physical organization is as follows:• Building L hosts HR and Finance Departments• Building M hosts HR and Security Departments• Building G hosts Media and Facility Departments• Building A hosts Security and Media Departments• Building K hosts main servers of all departments.The network requirement of each department is detailed as follow:HRNumber of employee 100Each employee has 01 PC + 01 IP PhoneThe department has 1 serverFinanceNumber of employee 50Each employee has 01 PC + 01 IP PhoneThe department has 1 serverMediaNumber of employee 50Each employee has 01 PC + 01 IP PhoneThe department has 1 serverFacilityNumber of employee 25Each employee has 01 PC + 01 IP PhoneThe department has 1 serverSecurityNumber of employee 10Each employee has 01 PC + 01 IP PhoneThe department has 2 serversAfter discussing with the Library management and their technical staff, both sides have agreed with the following technical requirements:• Each department should be placed on a separate SUBNET for management.• Departments located within the same building should use the same Layer-2 switches. VLAN must be used to separate traffics between departments.• Layer-3 switches must be used for routing between VLANs of the internal networks.• The network should be designed with high performance and high availability requirements using Ether channel and First Hop Redundancy technologies.• The company uses a single gateway router to access an outside router of ISP. Network Address Translation should be used on the gateway router to hide IP address of internal network.• The network should be designed to optimize the cost i.e. you should try to use least numbers of network devices and links.• The company was assigned the following IP address range to use for their networks: 185.XY.0.0/16 (XY is the last 2 digits of your student ID)Specific Assignment RequirementTo complete this assignment, you are recommended to take the steps below:1. Design and draw network topology using packet tracers (or other drawing tools). Clearly label the buildings, departments, switches and router. (10 marks)2. Identify how many subnets are required for your proposed topology. Design the subnets based on the given network address (185.XY.0.0/16) to optimize the address spaces (using the second approach – number of hosts needed). Note: the link between the gateway router of the university and ISP router has been assigned with network 192.1.X.0/24 (X is the first digits of your studentID).Create a table and provide details of the network design for each network such as below:HRAllocated subnet/MaskNetwork addressDefault gateway addressValid host address rangeBroadcast address(20 marks)3. Label the drawn network topology with corresponding subnets and ip addresses and then take screenshot(5 marks)4. Design appropriate configuration script for Routers and Switches to implement the proposed network. Where necessary, our configuration design should account for VLAN, Routing, NAT, and Redundancy.Place configuration of each device into a table as below:S1(Please type the script here as below, NOT using screenshot from packet tracer)S1: enableS1: configure terminal S1:. . .Then, enter the script into packet tracer to implement a functional network. (50 marks)5. Perform necessary verification to test the performance of the proposed network. All computers should be able to ping to any other computers on different networks and to the port on router. If either of the Layer 3 switches fails, the network should still be functional.Use necessary screenshots of ping and show commands on computers, switches and routers to show the status and performance of your network. (15 marks)SubmissionYou have to submit a design document as outlined above with a working packet tracer file to VU Collaborate Submission Box by the due date.DO NOT ZIP THE SUBMISSION FILESYou may be asked to demonstrate your solution a long with the document to the lecturer / lab tutor.
