You have been hired as the Network architect at an organization 3 days ago. As you walk into your office at 9:00 AM today, you see an email from your boss (the networking director - who has no network experience) that you must present the new network design to the board this afternoon at 2:00 PM. This is the first you are hearing of it. The new network design is expected to achieve the following work efficiencies: 1) Get rid of the flat network - currently everyone in the organization has a public IP address from the organization's 208.12.13.0/24 net block 2) Move everyone into a private network space in the 10.18.0.0/16 address space with the below VLANs a) Sales - 100 endpoints b) Marketing - 20 endpoints c) Management - 25 endpoints d) Admin staff - 200 endpoints e) Telephony - 150 endpoints f) Printers and fax machines - 25 endpoints g) internet-accessible servers - 3 endpoints h) Remote access gateways - 2 endpoints The network security team will handle the setup of the firewall and proxy, but you must break the network into 3 zones - the secure internal OSPF area, the DMZ OSPF area and the BGP AS for external network connectivity. All the above VLANs except (g) and (h) will reside in the internal zone - (g) and (h) will be in the DMZ. Provide a block network diagram showing the new network layout.

Split the 10.18.0.0/16 network appropriately for the VLANs. Make sure you have network addresses available for the network gear that is required to make this new network operational. Also provide IP addresses for the firewalls that will separate each of the zones. The firewalls will need two addresses per firewall - one for each of the zones the bring together. Also include a 500-word summary on any recommendations you have for the operation and management of this new network.
