QUESTION 1

!./c&+ &+c The 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).

0./c$&*+%c$)c- %)+ c 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.

-./c$&*+%c$)c 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

1./c -)c 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.

è./c $)c'$$c The 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.

4./c+ &$c+() &+c 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 µemmanuel¶ 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.

c + +c 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.
