You work for a company that has branches in different citics and you have been tasked to design the network for your organization. Your initial plan is to show a layer three topology diagram and then cascade down to more details. Task: a) Your first diagram is as shown below: Subnet 172.16.2.0/24 Subnet 172.16.4.0/24 GO/0 So/0/1 R2 Subnet 172.16.1.0/24 GOIO R1 .1 GO/1/0 Subnet 172.16.3.0/24 GO/O GO/O/D Subnet 172.16.5.0/24 Assuming R1 is for the central site and R2 is for a branch office, draw a detailed diagram that shows more detail about the physical cabling with less detail about the IP subnets and addresses connecting the central office with the branch office. Show all the labels and details appropriately. b) Armed with the cabling details (a) above, describe in detail how you can physically install a router ( Assumption: because your devices will be in the same place, you can create Ethernet WAN links by using the RJ-45 ports and a UTP cable without the need to purchase an SFP for each router).
