Question
Network Design
You will be creating the networks for the 4 LANs and the two internal point-to-point networks. You are given the 38.4.2.0/24 network to work with.
First create the Central LAN network, which will need to support 125 hosts. The second network will be the R1 Student LAN (VLAN 10), and will need to support 60 hosts. The third network will be the Faculty LAN (VLAN 20), which will need to support 22 hosts. The fourth networks will be the Staff LAN (VLAN 30) which will require 12 hosts. The fifth and sixth networks will be used to for the serial point-to-point links, and will each support 2 hosts. Note that there will be a small amount of unused address space when you have completed your subnetting.
For the LANs, assign the first usable address to the router interface, and the second to the PCs. For the Central LAN, you will also be assigning the last assignable address to switch S4 VLAN 1 interface. I recommend that you fill out the following table to keep things straight, but the table will not need to be submitted.
