All PCs can talk to each other. a) (6 marks) List the static routes implemented. Your answer should be in the format of the table below (Table 1): Table 1 For some reason the link between R1 and R3 was broken and removed. The network administrator managed to resume the traffic between the LANs using only four static routes. b) (6 marks) List the static routes implemented. Your answer should be in the format of the table below (Table 2): In Router 6 Static route(s) R1 R2 R3 In Router 4 Static route(s) Table 2 c) (6 marks) The company now decided to link the company network with the Internet.
