Cisco Networking Academy Program CCNA 2: Routing Protocols Protocols & Concepts v4
Dayne T. Barr Cisco – Semester 2
Overview and Objectives This case study allows students to complete a network design, im plementation, and troubleshooting project using the skills gained in CCNA 2. Students will use the skills that have already been developed to use, make, and connect the proper cabling to the appropriate devices. It is crucial to read and understand the scenarios to make sure that all requirements are fulfilled. Each scenario guides the student through the proper steps to ensure that the project is completed properly. This case study requires the student to accomplish the following tasks: Set up the physical layout of the network using the diagram and accompanying narrative o Correctly configure the routers with a basic router configuration o Correctly implement CIDR & VLSM strategies o Correctly configure summarized and default routes o Correctly configure EIGRP routing protocol o o Troubleshoot and test all connectivity Provide detailed documentation in a prescribed form, as listed in the deliverables section. o
Scenario and Phase 1: Project Description A company has several people responsible for maintaining various sections of the internetwork infrastructure. Many technicians have done an excellent job with the small portion for which they are responsible. One of the other network associates who was responsible for a larger portion of the infrastructure suddenly left the company. This left redesign and implementation on this portion of the internetwork unfinished. A technician is given the task to complete the design and implementation of the unfinished network. After taking home the documentation to study over the weekend, it is apparent to the technician why the network associate left suddenly. The few documents that existed were poorly written. So during the weekend the technician reconstructs the diagram above from an existing diagram that was found. It represents the new internetwork design. It shows the planned routers, hubs/switches, circuits, and the servers/workstations at each site. The server at the Center site is a file server accessed only by workstations on this internetwork. The workstation at the Center site is used to manage all routers on the internetwork. After returning to work Monday morning, the technician presents the new diagram to the Network Infrastructure Team Leader that assigned the project. After discussion, it is determined that new documentation must be developed for the project. The Team Leader, the instructor, must approve the documentation at each phase of the process. Use the following information to implement the network. Network address ___10.96.0.0 /12____
Phase 2: IP Addressing Now that the basic plan is in place, the team leader assigns the technician to develop a prototype for the new internetwork. Use the network address assigned along with the subnetting requirements, to subnet the network using VLSM. From the IP addressing scheme, assign IP addresses to the appropriate interfaces on all r outers and computers in the internetwork. Use the diagram on the following page as a guide. There are some special requirements. 1. General a. Use VLSM and Classless routing b. You will need to configure EIGRP as your routing protocol i. You may configure RIPv2 temporarily for testing, then remove RIP and configure EIGRP 2. Boaz location a. Do NOT advertise the networks connected to the loopback interfaces in your routing updates b. You will have NO static routes on this router (including default routes) 3. Eva location a. This router’s loopback 0 interface represents your connection to the Internet (default route) i. Propagate your default route through your routing updates b. It connects to the Center router through a serial port c. It connects to the Boaz router through an Ethernet port d. Use a single summary static route for the loopback networks on the Boaz router. 4. Center location a. The router’s interface on this LAN will use the highest usable IP address in the subnet. b. Use a single summary static route for the loopback networks on the Boaz router. c. You will have NO other static routes on this router (including default routes)
Obtain approval of this phase of development from the instructor before proceeding to Phase 3.

Case Study Deliverables The key lesson of this case study is the importance of thorough and clear documentation. There should be two types of documentation completed.
General Documentation: o
o
o
A complete narrative of the project should be typed using word processing software. Since the scenarios break up the entire task into pieces, take care to address each scenario task so that any layperson could understand that particular task. There can be NO technical jargon in the narrative o Microsoft Excel or another spreadsheet program could be used to simply list the equipment and serial numbers. Cisco Network Designer (CND), Microsoft Visio, or any paint program could be used to draw the network.
Technical Documentation: The technical documentation should include details of the network topology. Use CND, Visio, or any paint program to draw the network. Use the tables in the working copy of the case study as a reference, and enter all table information into a spreadsheet program such as Microsoft Excel. The spreadsheet should include the following details: IP addressing of all interfaces o DCE/DTE information o Router passwords o o Interface descriptions IP address ranges and gateway assignments for all subnetworks o Document the use of a routing protocol. Router output from the following commands should be captured and placed into this documentation: Each output should be on a separate page. o o o o o o o
show cdp neighbors show ip route show ip protocol show ip interface show version show hosts show startup-config
Accumulate all documentation and organize it into a 3 hole, report cover with fasteners. Include this document with your case study deliverables.
