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 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.

There are three Local Local Area Networks (LANs) (LANs) and two smaller networks which provide serial link connectivity between the LANs. The following information information will provide will be used used throughout this document and will be used for the network design process.

As sta state ted d in par parag agra raph ph 2.1 2.1.2 .2,, the the prov provid ided ed net netwo work rk add addre ress ss for for thi this s

project is 172.17.0.0/16. 172.17.0.0/16. This address space space will provide 65534 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 Subnet ....... ........... ....... ...172 172.17 .17.2. .2.0/2 0/24 4 Center - Eva Subnet.........172.17.3.0/30 Center - Boaz Subnet.......172.17.3.4/30 2.2.2 It is propose proposed d that the the serial serial link link subnets subnets will will become become /30 networks 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, networks, allowing a maximum maximum of 254 host’s each. This will allow for significant significant future expansion to each of the LAN networks and the distinct subnets will enable ease of configuration. To provide a logical logical addressing scheme 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 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. 2.2.3 3

The The netw networ ork k des desig ign n has has been been con const stru ruct cted ed and and test tested ed in the the Cisc Cisco o

propriety simulation software 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. 6


2.2. 2.2.3 3

To enab enable le eas ease e of of conf config igur urat atio ion n and and to assi assist st tec techn hnic icia ians ns when when

fault finding, each router has been given a unique hostname and for security passwords have been been set up. When trying to access the router a prompt 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. information. Here the user can also access the Configure Terminal Mode, where router configuration changes can be made. The passwords and and hostnames used for for this network, and used within the Packet Tracer Tracer software, are listed at Appendix 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. 2.2.4 4

One One of of the the req requi uire rem ments ents of the the pro proje ject ct is to set set up up a Tri Trivi vial al File File

Transfer Protocol (TFTP) (TFTP) server on one of of the workstations. After some investigation and research it has been discovered that to do this proprietary software needs to be installed on the the workstation. As there is a server server already within the network, it i t is recommended that this become the TFTP server, and the TFTP function within the server has been enabled in the Packet Tracer simulation software.

2.3

Routing Protocol 2.3.1 The routing routing protocol protocol recomm recommende ended d for this projec projectt is Open Shortest 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 and Johnson (2008: (2008: 500). Link-state protocols do do not exchange routes and metrics, they exchange only the state of the links they

7


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. RIP. Although very easy 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, 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 drawback with EIGRP is that it is specifically designed for Cisco Cisco routers. ‘EIGRP is an enhancement 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 disadvantages to using link state protocols, such 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 www.microsoft.com (2010). The size of the current network topology is not considered intensive for the routers to handle. 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, convergence, it minimizes minimizes bandwidth consumed consumed by routing information, using low bandwidth wisely, and it can take link bandwidth into account.

3.1

Summary 3.1.1 The solution solution provided provided covers covers all the the requireme requirements nts requeste requested d by the project. The proposed network is based based on the existing topology diagram 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 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.
