The purpose of this project is to provide an opportunity for students to apply network administration and design competencies gained throughout this course.

Deliverables

Please choose ANY FOUR options from the following five options and complete the report for your chosen four options (OPTION 1 is MANDATORY).

Option 1: Network Design Case (100 points)

Option 2: Windows Security Firewall (33.33 points)

Option 3: Configuring OSPF Routing (33.33 points)

Option 4: Configuring EIGRP Routing (33.33 points)

Option 5: IPv6 Address Configuration (33.33 points)

Option 1: Network Design Case

Scenario

Consider that the prevailing market conditions have made it possible for our firm to expand our current operations. I have presented several options to our board of directors and they are eager to proceed with an expansion except for one condition. The board feels that our current telecommunications infrastructure hinders our business operations and that it is imperative to design a new voice and data infrastructure to facilitate the planned expansion. The board is prepared to advocate any prudent expenditure necessary to implement a new infrastructure at the upcoming stockholder’s meeting.

As you know, our firm is headquartered in San Antonio where we occupy the first and third floor of a large, but somewhat antiquated building. Each floor of the building measures 400 ft. by 250 ft. We currently have 52 Pentium-based PC’s located on the third floor to meet the needs of our accounting, billing, and phone sales departments. The first floor contains 17 Pentium-based computers and six Apple PowerMacs used by management, our receptionist, walk-in sales staff, and our adjusters. We currently have a 10Base2 network that is used to connect some, but not all, of our existing systems. The previous network manager told us the remaining systems could not be networked due to the 10Base2 architecture. We also have smaller offices in Austin, Houston, and Corpus Christi. These offices generally have 4 to 6 Pentium or Apple-based computers. The computers in these locations are not currently networked.

Our immediate expansion plans, if approved by the shareholders, include opening a second office in Houston, two offices in Dallas and an office in El Paso. These offices will be similar to the existing small offices operated in Austin, Houston and Corpus Christi. My vision for the new telecommunications network includes having all of the existing and proposed offices connected together in a seamless, secure manner. All of the computers in all of the offices should be connected.

Deliverables:

· I need to understand whether or not we can continue to build on our current network and why. I also need to know what we should use to replace it if we need to do so.

· I see the network as consisting of two primary parts, the networks within each facility and the network that connects the various facilities together. Please provide diagrams that illustrate how these networks will look after the new infrastructure rollout (Also include a generic diagram for one of the branch offices).

· I will require a detailed cost proposal for both the installation and first year’s operating cost associated with the entire proposed infrastructure. You will need to consider all equipment and wiring costs, the cost for the proposed services from the phone companies and provide the source for your costing information (Excluding labor costs).

· Discuss the feasibility of implementing an IPv6 protocol along with our new infrastructure, and the business ramifications of implementing IPv6 at this time.

· Describe how security will be maintained for data, particularly for data being transmitted between offices and for wireless connectivity.

· Discuss how you will implement a network that will allow secure wireless communications between computers and other resources, including Internet access (Be sure to discuss steps for configuring wireless access points and wireless network adapter with various security features including WPS, WEP, WPA2, etc.).

Option 2: Windows Security Firewall

The overall objective of this laboratory exercise is to gain experience with the basic steps for configuring a personal firewall on Windows operating system (say Windows 7). In this exercise you will learn to create an inbound firewall rule and outbound firewall rule. The inbound firewall rule will only allow a ping packet from server (S1). The outbound firewall rule will block any web traffic from computer PC1 and computer PC2. Configure the computers to operate in the network using the IP addresses, subnet mask, and gateway address specified in Table 1. You will gain an understanding of the following:

1. Configure the Windows firewall.

2. Configure the Windows advanced firewall features.

3. Specific protocols and their network ports

PC1 192.168.3.1 255.255.255.192 192.168.3.62

Detailed Lab Steps

Task #1

1. Assume that you have already configured the IP addresses for computers PC1 and PC2, for Server, S1 and for router R1 (from previous labs).

2. In the next step, you are to make sure that the Windows firewall is enabled. List the step sequence required to verify the firewall status and to enable the firewall.

3. List the command sequence and steps required to create a new inbound firewall rule called “Ping Request” to allow only server S1 to ping PC1 and PC2. Make sure the correct protocol is selected for Ping.

4. If you have to verify the firewall rule “Ping Request” by initiating the Ping from S1 to PC1 and PC2, and then initiating ping from PC1 to PC2 and vice versa, explain which ping results of these ping request will pass and which will fail.

5. List the command sequence and steps required to create a new outbound firewall rule called “Web Filtering”. This rule is to block any web traffic initiated from PC1 and PC2. Be sure to block both unsecure and secure web traffic. Make sure the correct protocol and its associated ports are selected for web traffic. Explain the expected result if you have to initiate any web session from PC1 and PC2.

Option 3: Configuring OSPF Routing
