NETW204 Class Project

This project includes three phases. You need to complete Phase I before moving on to Phase II.

Likewise, you need to complete Phase II before moving on to Phase III or the final phase in the

project.

Hi-tech Net Corp. is operating in three locations in the United States. Their main office is

located in New York, NY. They have two branch offices located in Chicago, IL and Sacramento,

CA.

You have just been hired as Hi-tech Net Corp.’s consulting engineer to implement their network

infrastructure. Both branch offices will be directly connected to the main office in NY via a

leased line circuit (point-to-point serial connection).

New York’s Office IP Information

The main office has four LAN segments: Executive, Engineering, Services, and

Native&Management. Each LAN segment is identified by a VLAN number as seen below. For

example:

 Executive: VLAN 15

 Engineering: VLAN 25

 Services: VLAN 35

 Native&Management: VLAN 99

The organization is using the following network address in NY: 10.150.0.0/16.

 Executive: 60 computers only including future growth in this number

 Engineering: 80 computers only including future growth in this number

 Services: 115 computers including future growth in this number

 Native&Management: 12 computers including future growth in this number

*** Future growth means that we already take growth into consideration. Do not try to

estimate or add more IP addresses than necessary to avoid getting an incorrect subnet.

Illinois’ Office IP Information

The IL branch has three LAN subnets with 45 IP addresses on each subnet. They use the

following network address to obtain the required IL subnets: 10.150.100.0 /24.

California’s Office IP Information

The CA branch has three LAN subnets with 25 IP addresses on each subnet. They use the

following network address to obtain the required CA subnets: 10.150.200.0 /25.

PHASE I (20 points total)—Due Week 3

Tasks to Do.

Task 1: Subnet the 10.150.0.0/16 network for NY and assign the first subnets to Services

followed by Engineering. You may need to re-subnet for Executive and Native&Management

subnets to avoid wasting IP addresses. Ensure that you re-subnet only the first unused subnet

and nothing else. Assign the subnets to Executive and Native&Management. (5 points)

Task 2: Subnet the 10.150.100.0 /25 network for IL and assign the last IP address on the three

subnets to the Loopback 1, Loopback 2, and Loopback 3 interfaces of the router. We will use a

loopback or virtual interface to simulate the LAN subnets. This will speed up configuration and

allows us to create our topology without rewiring. (3 points)

Task 3: Subnet the 10.150.200.0 /25 network for CA and assign the last IP address on the three

subnets to the Loopback 1, Loopback 2, and Loopback 3 interfaces of the router. We will use a

loopback or virtual interface to simulate the LAN subnets. This will speed up configuration and

allows us to create our topology without rewiring. (3 points)

Task 4: Use the following network address (10.1.255.0/25) to find the WAN subnets between

NY and IL and NY and CA respectively. Note that there should only be two IP addresses per

subnet for each WAN link. Assign the first WAN subnet to NY to IL and the second WAN subnet

to NY to CA. (2 points)

Task 5: Use Microsoft Visio to design the current network topology. Remember to use

Loopback interfaces for the subnets in NY, IL, and CA. Use point-to-point interfaces to connect

the remote branch offices to NY. See the sample network diagram below. Replace the phrase

“IP Address” by the correct IP address for each interface on the routers. Include the WAN IP

addresses on the diagram as well. (7 points)

First Major Deliverable in the Project: IP scheme for all three locations (fill in the IP tables

above) and the Visio Diagram.
