QUESTION 1

1.0 INTRODUCTIONThe design of this network implements the virtue connection of ISP router with the head quarter with

multiple locations, two to be précised. Communication within the routers is via enhanced interior gateway

routing protocol (EIGRP).

2.0 NETWORK DESIGN BACKGROUND This report is a routing design for UK based travel agency (UKTA). This report use enhanced interior

gateway routing protocol (EIGRP) for design and implementation of interconnected multiple locations

from single internet service provider. This network logical topology consist of four network directly

connected to the head quarter router. A total of three routers are used in this network, this routers are

configured to implement EIGRP routing protocol within the network.

Figure 1: network topology

From the network design above both the physical and logical network topology can be obtained. Using

the above topology an address scheme was created to accommodate the entire host in the network. For

achieving this, the private internetwork protocol provided 192.168.156.0/22 needs to be sub-netted.

3.0 NETWORK DESIGN The network design consists of three routers, HQ, REMOTE 1 and REMOTE 2. REMOTE 1 and

REMOTE 2 are connected to HQ via WAN. Other connected network is Fa0/0 and Fa0/1 on the HQ

router and same for REMOTE 1 and REMOTE 2.

Figure 2: network design

4.0 CABLING While design this network assumption where made based on the number of host of each subnet. Each

subnet where allocated required amount of switch necessary for connection of host. HQ Fa0/0 was

allocated 5 switches, Fa0/1 three switches, REMOTE1 Fa0/0 two switches, Fa0/1 three switches,

REMOTE2 Fa0/1 three switches and Fa0/0 six switches In most case extra port where left this is meant

for use in case of physical growth of the network topology. WAN connection is used for connection

within the router, straight through cable is used for connecting router to switch and switch to pc, while

cross over is used for connection between switch to switch.

5.0 ADDRESSING SCHEMEThe private network address of 192.168.156.0/22 has been given. EIGRP being a distance vector routing

protocol is used for routers packet transfer and communication. EIGRP being a classless routing protocol

support variable length subnet mask. Classless internetwork protocol was used to design the addressing

range for the devices in this network, helping in making maximum use of the ip and limiting ip wastage

as possible.

The addressing given was sub-netted to provide the eight available subnet address used for this network.

The first sub-netting starts from HQ Fa0/0 subnet. This reason why the subnet was start at the HQ Fa0/0

is because it had the highest number of host in the HQ, grouping them into the same sub-net will provide

sharing of resources.

Loopback interface address given 189.54.69.234/30 was assigned for it designated subnet. This is because

the ISP router is a virtual interface for management purpose. Unlike the proper loopback address that is

used for ping within system this is used within the network, it does not talk back at itself. The ISP router

is a virtue router because first it don not exist in the network topology but is used because most loopback

functionality is provided by ISP router.

Please see below table for address scheme.

QUESTION 2

8.0 ROUTER CONFIGURATION Using Cisco packet tracer environment, a network topology was create as shown below. This network

comprises of HQ router, REMOTE 1 and REMOTE 2 routers interconnected by WAN.

Figure 3: router connection

The router was all configured using EIGRP process 1. All connected networks were advertised except the

loopback interface, this was done to ensure communication throughout the network using EIGRP. Default

route was configured on the HQ router as a static route which was distributed through EIGRP to

REMOTE 1 and REMOTE 2. REMOTE1 is connected to the HQ router via S0/0/1 and S0/0/1 on

REMOTE1 on router. REMOTE 1 subnet is connecting via Fa0/1 and Fa0/0 to the REMOTE1 router.

REMOTE 2 subnets are connected via Fa0/0 and Fa0/1 on the REMOTE2 router. HQ router are connect

through Fa0/0 and Fa0/1 on the HQ router.

Due the router were not configured with password be EIGRP was configured. Secret password was set to

‘emmanuel’ for all three routers. This was done for security purpose. To prevent unauthorized up set of

router configuration. Configuration of EIGRP on the three router forms an autonomous systems.

11.0 TESTING Test plan have been developed to check the network device ability to communicate with each other. Basic

ping is to be carried out, pinging each interface from each location. EIGRP specific test are carried out to

ensure EIGRP protocol used on the router is functioning correctly. This includes testing convergence and

cdp.

CONCLUSION UKTA network is design to conform to all network standards. The network topology support high level of

scalability, Qos and security within the network. Extra port on the router was left to support physical

scalability within each subnet for logical increase internwork protocol could be sub-netted to get required

IPs. Based on the UKTA scenario routers were successfully configured to use EIGRP protocol for

communication within the network forming an autonomous group. The HQ was configured with loopback

address meant for the network and a static route was also configured for a virtue communication with the

network.
