On your topology you should do: Use at least 6 routers and 3 switches. It should contain 3 LANs: IT with 12000 users, CS with 6000 users, and CE with 3000 users departments. NOTE: use the CIDR technique to avoid wasting IP addresses. Specify the cables types. Between router use, for IP address, the first byte will be the last two-digit from student 1 ID, for LANS first byte will be the last two-digit from student 2 ID. Between routers use class c IP addresses. On your topology you should do: Use at least 6 routers and 3 switches.
