Institution: Network Design and Configuration - TCP/IP Report

This report presents a comprehensive overview of a TCP/IP network design and configuration. The network comprises three client PCs, two routers, two switches, and three servers (DHCP, DNS, and Web Server). The report details the configuration of routers, including routing protocols, and the setup of IP addresses for all devices. It includes command configurations for routers (R0 and R1), along with network addressing diagrams. The report explains DHCP and Web server configurations, including the assignment of IP addresses by the DHCP server, DNS record creation, and HTTP configuration on the Web Server. It also includes ping tests, trace route tests, and simulation panel results to demonstrate network communication. The report concludes that the network is functioning correctly, with devices communicating effectively across different networks, ensuring scalability and security through firewall implementation.

Introduction
Networking is one of the significant areas that need a lot of care and consideration in order to
avoid making mistakes that will affect the goals and objectives of the organization. In setting a network
key factors such as scalability, security, cost and maintenance must be ensured that they favors the
organization or an individual in full. Ideally, for one to have a good network then one must be able to
design the setup, install all the devices and configure depending on what one think will meet or satisfy
the desires of the organization.
This report aims at ensuring that one can be able to set up different networks such as having the clients,
the switch, routers and servers and in this case the PCs and Servers have different networks. In this case,
the idea is to configure the routers and servers with the best routing protocol. The other concept is
being able to configure the DHCP servers, WEBs Servers and DNS among others.
Setting up the Network
The network comprises of three clients PCs, two routers, two switches and three servers namely the
DHCP, DNS and Web Server respectively as shown below.
Client(s) <--> Switch <--> Router <--> Router <--> Switch <--> Server(s)
The above have been represented as follows in this case clearly showing how such diagrams have been setup and
configured.

DHCP and WEB server Configuration
Figure 13 DHCP configuration
The following diagram has been used in explaining the configuration of a DHCP. In this case there are
two networks with two pool names that is Pool1 and Pool2 where each pool has got its own IP network
address.

Conclusion
As seen from above it is true to say that the network are communicating with each other and that one
can send information from device to the other in different networks as clearly shown above. As shown in
the ping test and trace route test it is very much clear that the PCS are communicating clearly with the
servers. In this case, it will be true to say that all the devices are connecting efficiently in all essences and
that the network will be scalable in all ways in case there is need for expansion in future. Use of firewalls
on the web server will help in filtering the traffic the https files and thus ensuring that there is security in
the system.
