Question 1 A small business, Smart Office Services Pty Ltd, has its central office (HQ) and two branch offices (Branch 1 and Branch 2) linked via serial leased lines using routers. The network topology is given as follows. It is required that: 1) You will be assigned a single IP to configure this network. 2) You must e-mail your lecturer to request an IP address. Once you have received your allocated IP address you need to reply with a confirmation e-mail. Study the network topology, examine the network requirements, set up the network in Packet Tracer and complete all five sub-questions. Keep in mind that IP addresses will be needed for each of the LAN interfaces. Follow VLSM scheme to identify the different subnets according to network requirements. Please analyse and design the best IP addressing scheme. Create a table which lists the following information: Router Interfaces/ IP Address (Highest)/ IP Address (Lowest)/ Subnet Mask/ Default Gateway). Please show working out. Note: The lowest IP addresses of each subnet should be given to the PCs. The highest IP addresses of each subnet are given as the default gateway. Note: USE NETWORK ID : 115.41.0.0 SUBNET MASK: 255.255.252.0 Question 2 Follow previous questions' requirement, set up your network in Packet Tracer simulation software. Configure the three (3) routers: - name the routers and label them as HQ, Branch1 and Branch 2 (3 marks) - set the secret password as 'class' on all routers (3 mark) - configure interfaces/ PCs (3 marks) - configure TELNET on the HQ router with a password of 'xyz123' and (a suitable) MOTD (3 marks) - Verify basic configuration and router operations (3 marks) Question 3 Configure the other PCs and configure the necessary static routes (such as IP route 0.0.0.0 0.0.0.0 exit interface) on three routers to make a successful connection between routers. "Show ip route" check and screen shot each router's routing table. Question 4 PING from PC6 in LAN6 to PC4 in LAN4 (checked in Packet Tracer file). What protocol is used by PING? What are the names of two PING messages? Provide screen shots of successful ping (2 marks) Record the information flow in EVENT LIST of simulation and explain the PDU information such as TYPE and involved layers in each stage (6 marks) Rationale This assessment task covers topics (IP Addressing,VLSM design, Router Configuration,etc.) and has been designed to ensure that you are engaging with the subject content on a regular basis. More specifically it seeks to assess your ability to: - design a subnet plan for a small company network including several routers and subnets; - discuss routing problems that can occur in complex networks; - correctly identify and discuss the functionality and limitations of different devices used in computer networks; - evaluate network performance; - perform basic router configuration of security passwords and interfaces; - configure simple routing. Marking criteria The following criteria are designed to guide you in your presentation and preparation of your assignment. The criteria apply generally across all questions to show you the standard required for each of the criteria. Criteria Accuracy All questions and procedures articulated and applied clearly and concisely, all calculations are successful and complete, appropriate hardware identified and described clearly and concisely.
