Waterloo will have 2 subnets: i) Office1 ii) Office2 and it uses a private IP: 172.20.0.0/16

Brampton will have 2 subnets: i) Office1 ii) Office2 and it uses a private IP: 172.40.0.0/16
Your tasks are to network all branches, provide internet connectivity, e-mail services, remote
connectivity between other branches and Toronto, deploying other related servers as described
by the following questions:
1. Provide a LAN solution for each office connecting the computers together. What network
topology you are going to use for different LANs and why? Explain all connectivity devices
used by your selected topology. (5 points)
2. Provide a solution for IP address assignment for the above offices. You need to explain the
type of IP address assignment (static/automatic), how the total solution is going to work and
