Design a network in CISCO Packet Tracer for two different companies in such a way that all the PCs in each company must be able to communicate with each other as well as with all the PCs of any other company. Suppose each company has three PCs that are connected via a switch. The first switch is connected to router Ro and the second to router R1. The first company network IP address is 192.168 .40 .0 and the second company IP address is 192.168.50.0. Use Generic Router, Generic Switch, and Generic PCs for your design. a. Draw the topology of the network. (4 marks) b. Show how the devices are connected using appropriate cables. (2 marks) c. Use the above information to configure all interfaces with appropriate IP addresses, subnet masks, and gateways for each of the devices. Assign static IP information to the PC interfaces (Hint: Write ALL the addresses for each device in your worksheet). (24 marks) d. Verify your network connectivity between the two company's PCs (You should include a screenshot of the packet transmission in your worksheet). (10 marks) e. Record a video (maximum 2 minutes) of your network configuration to demonstrate the packet transmission.
