Network Routing and Fundamentals Case Study 2
1.0 OVERVIEW AND OBJECTIVES
1.1 Introduction
A unit 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 was suddenly posted. 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.
The few documents that existed were poorly written. So during the weekend the
technician reconstructs the diagram from an existing diagram that was found. It
represents the new internetwork design. It shows the planned routers, hubs
/switches, circuits, and the servers/ workstation 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,
shown at Figure 1 to their network infrastructure team leader that assigned the
project. After discussion, it is determined that the new documentation must be
developed for the project.
1.2 Requirements
1.2.1 This Project has the following requirements:
Set up the physical layout of the network using the provided diagram
and accompanying narrative.
Correctly configure the routers with a basic router configuration.
Set up a TFTP server on one of the workstations.
Troubleshoot and test all connectivity.
Provide detailed documentation that is logically organised to make
troubleshooting easier.

2.0 TECHNICAL SOLUTION
2.1 Existing Topology
2.1.1 The original network topology diagram has been provided and is
shown at Figure 1 below. The topology has been checked and is correct, so
this to form the basis of the new network design.
4
Network Routing and Fundamentals Case Study 2
2.1.2 The information gleaned from Figure 1 shows that there are five distinct
networks within the topology. There are three Local Area Networks (LANs)
and two smaller networks which provide serial link connectivity between the
LANs. The following information will provide will be used throughout this
document and will be used for the network design process.
Provided Network Address: 172.17.0.0/16
Required Number of Subnets: 5
Routing Protocol: Open Shortest Path First (OSPF)
2.2 Internet Protocol Range & Router Configuration
2.2.1 As stated in paragraph 2.1.2, the provided network address for this
project is 172.17.0.0/16. This address space will provide 65534 Internet
Protocol (IP) addresses which far exceeds the requirements for this network.
Using Variable Length Subnet Masking (VLSM), it is recommended that the
address space be reduced and is that it is sub-netted as shown in Tables 1
through to 5 at Appendix 1, page 11 and as summarised here:
Boaz LAN Subnet.............172.17.0.0/24
Center LAN Subnet..........172.17.1.0/24
Eva LAN Subnet ..............172.17.2.0/24
Center - Eva Subnet.........172.17.3.0/30
Center - Boaz Subnet.......172.17.3.4/30
2.2.2 It is proposed that the serial link subnets will become /30 networks
providing 2 usable host addresses; each serial link requires only 2 host
addresses, one for each end. The three LANs will become /24 networks,
allowing a maximum of 254 host’s each. This will allow for significant future
expansion to each of the LAN networks and the distinct subnets will enable
ease of configuration. To provide a logical addressing scheme which is
common across the subnets, each LAN will use the first usable address for
the router Fast Ethernet interface and the second address is used for the
5
Network Routing and Fundamentals Case Study 2
Switch VLAN. The remaining addresses are used by the workstations and
server, starting with the last usable address and working backwards.
Configuration tables for each network can be found at Appendix 2, Page 13.
2.2.3 The network design has been constructed and tested in the Cisco
propriety simulation software called Packet Tracer. A network topology
printout from Packet Tracer can be found at Appendix 3, page 14, and Show
commands for each router can be found at Appendix 5a – g on pages 16 –
39.
2.2.3 To enable ease of configuration and to assist technicians when
fault finding, each router has been given a unique hostname and for security
passwords have been set up. When trying to access the router a prompt will
ask the user to enter a password which will allow him access to User Exec
Mode, a mode which will allow him to monitor things only. A second
password is then required to enter Privileged Exec Mode, a mode which
allows the user to gain detailed information. Here the user can also access
the Configure Terminal Mode, where router configuration changes can be
made. The passwords and hostnames used for this network, and used within
the Packet Tracer software, are listed at Appendix 4, page 15. Once the
network is constructed, the passwords shown here should be changed and
should be kept in a secure location.
2.2.4 One of the requirements of the project is to set up a Trivial File
Transfer Protocol (TFTP) server on one of the workstations. After some
investigation and research it has been discovered that to do this proprietary
software needs to be installed on the workstation. As there is a server
already within the network, it is recommended that this become the TFTP
server, and the TFTP function within the server has been enabled in the
Packet Tracer simulation software.

Network Routing and Fundamentals Case Study 2
2.3 Routing Protocol
2.3.1 The routing protocol recommended for this project is Open Shortest
Path First (OSPF). OSPF is a ‘Link-state protocol that was developed as a
replacement for the distance vector routing protocol Routing Information
Protocol (RIP)’ Graziani and Johnson (2008: 500). Link-state protocols do not
exchange routes and metrics, they exchange only the state of the links they
know about, and the cost associated with those links. This saves
considerably on bandwidth.
The other protocols considered are Enhanced Interior Gateway Routing
Protocol (EIGRP) and RIP. Although very easy to configure, RIP has been
discounted as the routing protocol because of drawbacks such as it can only
be used in networks that have fewer than 15 hops, it converges slowly on
larger networks, it is prone to routing loops and routing updates can require
significant bandwidth because the entire routing table is sent. TechRepublic
(2004)
EIGRP was also considered but is not recommended as it is a Cisco
proprietary protocol. The major drawback with EIGRP is that it is specifically
designed for Cisco routers. ‘EIGRP is an enhancement of Cisco Interior
Gateway Routing Protocol (IGRP) and will only operate on Cisco routers’
Graziani and Johnson (2008: 392). Therefore EIGRP would require that only
Cisco equipment be used in any future expansion of the network unless a new
routing protocol was introduced throughout the network at the same time.
There are disadvantages to using link state protocols, such as OSPF. They
are resource intensive and require more processor capacity and memory.
‘For very large internetworks, the database of link state advertisements and
the calculation of routing table entries can be memory and processor
intensive.’ . www.microsoft.com (2010). The size of the current network
topology is not considered intensive for the routers to handle.
7
Network Routing and Fundamentals Case Study 2
OSPF has been recommended because this protocol is an open source
routing protocol and is used commonly on most routers from most
manufacturers. It has fast convergence, it minimizes bandwidth consumed by
routing information, using low bandwidth wisely, and it can take link bandwidth
into account.
3.0 SUMMARY
3.1 Summary
3.1.1 The solution provided covers all the requirements requested by the
project. The proposed network is based on the existing topology diagram and
the solution will be easily managed and can be scaled for future growth. The
network addressing scheme has been derived from sub-netting the allocated
address space into manageable subnets with logical allocation of IP
addresses whilst leaving significant room for future expansion.
The two main routing protocols considered were EIGRP and OSPF. Although
OSPF is slightly more complex to configure and understand than EIGRP, it is
the recommended protocol due to EIGRP being Cisco proprietary.
