Change the internal network address to incorporate variable

Question

Suppose the image below is your company's network diagram after a merger and you have recently added access controls to your network. The CSO would like to:

• Change the internal network address to incorporate variable length subnet mask (VLSM) with EIGRP routing protocol.
• Set up all of the accountants on a separate VLAN.
• Create a VPN connection to allow accountants to access the accounting database from their home.

Write a two to three (2-3) page paper in which you:

1. Re-create the diagram provided in the assignment summary using VLSM, through the use of graphical tools in Microsoft Visio or an open source alternative such as Dia. (The starting address is 172.16.0.0.) Note: The graphically depicted solution is not included in the required page length. 
2. Specify the commands that you would use to set up the routers to use EIGRP.
3. Outline the requirements to set up a VLAN and VPN access for the accountants.
4. Specify the VLAN assignment, and incorporate a Spanning Tree protocol into your design to eliminate loops.
