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) For the private IP address, use the last 4 digits of your student ID as the first two octets of your network address. Keep other bits the same as shown in the addressing table and the figure below. For example, if your student ID is 12345678, using the last 4 digits (5678), so your main network address will be 56.78.0.0/16 [ my student ID is 11723960] Study the network topology, examine the network requirements, set up the network in Packet Tracer and complete all four sub-questions. Keep in mind that IP addresses will be needed for each of the LAN interfaces.

Keep in mind that IP addresses will be needed for each of the LAN interfaces. Question 3: (10 marks) 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. Question 4: (15 marks) 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 (2 marks) - Set the secret password as ‘class’ on all routers (2 mark) - configure interfaces/ PCs (2 marks) - Configure TELNET on the HQ router with a password of ‘CISCO’ and (a suitable) MOTD (3 marks) - Verify basic configuration and router operations (3 marks) - What are the main components of a Cisco router? ( 1 mark ) - You need to keep a back up of IOS of the routers. Please advise the two methods with correct procedures.(2 marks) Question 5: (3 marks) 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 6: (5 marks) 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 (1 mark) Record the information flow in EVENT LIST of simulation and explain the PDU information such as TYPE and involved layers in each stage (2 marks). Troubleshoot connectivity issues if pings were not successful, and write down your reflection of how to conduct a good connectivity test (2 marks). Note: You are expected to submit your assignment solutions in word or pdf file. Packet tracer file must be submitted for the supporting evidence of assignment Part B.
