CTNWK603 Plan, configure and test advanced internetwork routing solutions Assessment 02 Warwick institute of Australia
The following case study is used to illustrate the process and documentation required for a network design. This case study presents a scenario in which the UBack Company has hired a Network Consultant Group to design their network. In order to help you organize this project, the scenario has been broken into eight phases listing requirements for each phase. A worksheet is to be completed for each part. A formal report, similar to what would be given to the company, will need to be created after all tasks have been completed. This case study requires that you accomplish the following:
Logical diagram:
The UBack Company is small company that is developing high-speed wireless products. The main office occupies two buildings in Sydney. One building is for the Administration Group. The other building is for the Sales and Marketing Group, and the larger Research and Development Group. The Research Group and the Sales and Marketing Group will each have employees located on all three floors of the main building. The UBack Company also has a Sales Branch Office located in Melbourne. The Company is implementing a wired network that should support 100% growth over the next five to ten years. A logical diagram has been provided. The task is to design, implement and fully document the UBack Research Company network. In addition to a formal report, the UBack would like to see a prototype of the network built, before it is fully implemented, to verify that it will meet the company’s needs.
Phase 1: Requirements
Requirements
The UBack Company has provided a partially completed logical diagram of the required network. The company has also provided networking equipment for development and demonstration. In some instances the equipment provided does not have all the required LAN interfaces. If this is so the company allows
Configuration of loopback networks, as alternatives.

The tables and supporting text will be part of the documentation delivered to the UBACK Company.
Before you commence with the next task the logical diagram and tables need to be approved by the company.
Phase 2: Routing protocols
The company wants a recommendation for a routing protocol for the network.
Worksheet
The possible routing protocol alternatives and properties are to be identified in a brain storming session. Each property is assigned a plus, neutral, or minus value for each of the routing protocols. Alternatively a numerical value can be used, for example 0 to 4. A recommendation is made and the decision matrix presented to the Company.
Routing Protocol |
Property 1 (+, neutral, - , or a numeric value) Supports VLSM |
Property 2 Scalable Uses multicast updates |
Property 3 Easy to configure |
Property 4 Proprietary |

Phase 3: OSPF
The Company has decided that it will use OSPF as the routing protocol.
UBACK Company Requirements
Phase 4: VLANs
The company now wants information about VLANs. These are required in the Main Building. The company has provided the following information:

The table below is an example of the documentation that the company requires.
Switch Details

VLAN Port Assignments
Update the switch tables, located in the worksheets of Scenario (part 2), with the VLAN and port information for each server, workstation, interconnect between switches, and the interconnect to the router in the Main building
Phase 5: Physical layer design
The Company needs a proposal which will include the growth projections for the physical layer design.
The document should include the number of cable runs, recommended equipment including patch panels, and labeling rules must also be specified.
For each floor, a table similar to the one below should be included in the documentation.

To help with the physical layer design the company has provided a diagram from their old site. The company requires a similar diagram for the Main Building. The Main Building has three floors and will use Cat 5 throughout for the LANs.
The diagram must include the following:
.
On each floor the horizontal cable runs will be no more than 30 meters. The length of cable needed between consecutive floors is 15 meters.
The documentation should include a description of how cross connects for all trunks will be patched for the required logical topology. The pin out (straight or crossover) cable types should be listed.
Phase 6: Test network
The Company requires a demonstration of the functionality of the Main Building network and asks that a logically equivalent network be wired up with the equipment provided. The company requires an http server machine to be set up in the Server VLAN and a minimum of a single client host on each of the other VLANs. The company requires that all devices be configured. All configurations, routing tables and VLAN databases are to be recorded as part of documentation.
The company specifies the following network testing. The company is receptive to suggestions or recommendations about other testing and about future network improvements.

Phase 7: Final demonstration
The company now wants a demonstration of the complete company internetwork. All devices are to be configured and access to the Internet Server address from all networks shown. The OSPF routing protocol with process id of 50 has been selected. Because the network is quite small, a single OSPF area is acceptable.
All configurations, routing tables, and outputs from connectivity testing are to be recorded and stored on a tftp server and on floppy disk.

Phase 8: Presentation
The final task in this case study is to deliver a 10-minute presentation of the main features of the design decisions and recommendations. A formal written report should also be provided that contains all of the design documents as well as all the supporting worksheets (see case study deliverables). The document should be complete enough to allow a third party to install and configure the network without any additional documents.
Project Deliverables
Once the case study problem has been solved, the network has been successfully designed and the prototype implemented and tested, a final report must be provided to your instructor. This report will include thorough and well-organized documentation of the process. It is highly recommended that all tables be completed using a spreadsheet program such as Microsoft Excel. Cisco Network Designer, Visio or a paint program can be used for the network diagrams.
Student has to submit the following items must be included in the final report (Up to Phase5):
