Question

In Chapter 1, “Analyzing Business Goals and Constraints,” you first learned about ElectroMyCycle, a manufacturer of electric motorcycles. Now, ElectroMyCycle has chosen you to design a new network that will let the company scale to a larger size. In Chapter 5, you learned that ElectroMyCycle’s network will support about 200 employees. The network will include a data center and a new state-of-the-art manufacturing facility. Users in the campus network will access the servers in the data center from their PCs. To support online sales, ElectroMyCycle plans to have a DMZ that connects a web server, a DNS server, and an email server. ElectroMyCycle recently has opened a new branch sales office in a city that is about 500 miles from ElectroMyCycle’s headquarters.

Design and document an IP addressing scheme to meet these needs. Specify which IP address blocks will be assigned to each modules of your network design. Document whether you will use public or private addressing for each module. The ISP has assigned ElectroMyCycle the public address 184.104.130.0/28. Document whether you will use manual or dynamic addressing for each module. Computer the route summarization and a naming structure.

1. Create the network in the Packet Tracer to include:

1. Assign an IP address to all devices that require a static address
2. DHCP services
3. Rename the web page to include the team’s number, such as Team X.edu
4. Rename the web site soit.edu
5. Set up a DNS service for the web site
6. Set up an Email server and create accounts for at least two users each in Engineering, Manufacturing, and Sales
7. Annotate each device using your naming convention
8. Annotate IP address of all devices with a static IP address
   

Neither VLANs nor NATs are required to be configured in Packet Tracer for this assignment (we will cover these topics later this semester). Include the remote site on the Packet Tracer network, however, other than assigning IP addresses, you do not need to assign services.

2. Given the subnets and the number of users; assign each subnet an IPv4 address with CIDR, broadcast, and default gateway. (20 points)

LAN	Number of users	Sub-network address with CIDR	Broadcast Address	Default Gateway
Engineers	30	192.168.1.0/24	192.168.1.255	192.168.1.1
Manufacturing	130	192.168.2.0/24	192.168.2.255	192.168.2.1
Sales	20	192.168.3.0/24	192.168.3.255	192.168.3.1
F&A	10	192.168.4.0/24	192.168.4.255	192.168.4.1
Data Center	---	192.168.5.0/24	192.168.5.255	192.168.5.1
DMZ	---	192.168.6.0/24	192.168.6.255	192.168.6.1
Remote Sales Branch	10	192.168.7.0/24	192.168.7.255	192.168.7.1

3. Which devices will have an IP assigned manually? Which devices will receive IP addresses dynamically? Why? (5 points)
   the devices you want to add IPs top manually would be the routers, servers, printers and the firewall
   
4. Insert a screenshot of the network pools – if pools cannot be easily seen, list the contents of each pool. (10 points)

5. List the content of the NAT Servers. (10 points)

6. Provide the address or addresses with subnet mask for route summarization? (10 points)
   192.168.1.0/24 255.255.252.0

192.168.2.0/24 255.255.252.0           

192.168.3.0/24 255.255.252.0

192.168.4.0/24 255.255.252.0

192.168.5.0/24 255.255.252.0

192.168.6.0/24 255.255.252.0

192.168.7.0/24 255.255.252.0

7. Describe and document your naming convention. Give examples of your scheme. (5 points)
   
   
8. In this document, submit a screenshot of the network diagram; ensure all devices are properly annotated (20 points).
   
   
9. Insert a screenshot of the Web Page being displayed in the browser (10 points).
   
   
10. Insert a screenshot of an email delivered to a host (10 points).

Answer 1

Logical Network topology:

The logical topology of the network is shown in the form of three diagrams. First figure shows how the LAN and DMZ are connected to the internet. The second figure shows the three layers (core, distribution and access) of Electro My Cycle Company’s LAN. The third figure throws light on the T-1 link present between Electro My Cycle Company’s headquarters and their branch sales office (500 miles away from the HQ).

It can be seen that the DMZ is separated from the LAN which contains the workstations, Manufacturing facility and the data center. However, a link (shown in brown) has been provided from the Web server (DMZ) to the data center (LAN). This is present because the data backup of web server is present on the data center servers.

In this figure, it is clear that the LAN of Electro My Cycle Company has been logically divided into three layers – core distribution and access. Core layer contains the router that connects the LAN to ISP and DMZ and the switch via which the connection gets distributed in the LAN.

The PCs shown in the figure shows the facility where in 200 employees will be accommodated (including the engineers).

As shown in the diagram, either a T-1 link can be used or a Metro Ethernet virtual link can be used to connect both the facilities.
