University Network Design and Configuration Project

This assignment details the design and implementation of a client-server network architecture. It begins with the physical setup, including routers, servers (DNS, Web, DHCP), and PCs, along with their respective IP addresses and interfaces. The solution covers the configuration of IP addresses on routers, servers, and PCs, followed by the implementation of the EIGRP routing protocol. It includes client ping results and traceroute analysis to verify network connectivity. Furthermore, the assignment explores the configuration of network services such as DHCP, web server setup, and DNS configuration. The final section demonstrates firewall settings to control network traffic, providing a comprehensive overview of network design and configuration principles.

Task 1: Setting up a network
Introduction
The network setup is about implementation of a Client-Server architecture. Here, the
client devices or the PCs are connected together with a switch that connects to the router’s
gateway. The signal sent from the PCs are transmitted to other routers on the way to the final
destination or the network location of the servers. The network design is shown below:

Network Devices
 Routers: Four Routers (i.e. Router0, Router1, Router2 and Router3) are
interconnected together.
 Servers: Three Servers (i.e. DNS Server, Web Server and DHCP Server) are
individually connected to the three individual routers (i.e. Router0, Router1 and
Router2) respectively.

 PCs: Three Computers are connected together through a switch.

Configuring IP Addresses
The fact that a router does not have any inbuilt display or button for its configuration, it is
required to be connected with another PC through the console cable to access the command line
interface of a router where various codes are applied for its configuration.
The commands used for IP configuration in the routers are shown below:
Fig 2: IP Configuration in Router0
The commands used in the above configuration is explained below: At the very first the
router remains in the user exec mode where the ‘>’ symbol is present after the router’s hostname.

5RESEARCH NETWORK DESIGN
Then it is required to move to the privileged exec mode where the ‘#’ symbol is present after the
hostname. Difference between these two exec mode is that user exec mode support a few number
of commands only where as privileged exec mode support multiple numbers of commands that
the user exec mode. To enter privileged exec mode the command ‘enable’ is used. Now, if any
changes is required in the configuration then these two modes will not help with it, another
‘global configuration mode’ has to be opened by just giving the command ‘configure terminal’.
In the configure terminal for setting IP addresses on any interface it is first required to select that
interface by providing the interface name after the command ‘interface’. It will open up
configuration at the interface level, there use the command ‘IP Address’ then the ip address and
again type exit to get out of the interface level. Thereafter enter Ctrl+Z to save the configuration.
The same configuration method applies for all the other routers as well.

The IP configuration in the rest of the devices i.e. the servers and the PCs are similar
where first move to the ‘network and sharing centre’ and right click on the interface name. There
in properties the below screen will be found for IP configuration.

Routing Protocol Configuration
Routing Protocols specify how the routers communicates or transmits data with each
other. Various routing protocols are available. However, in this assignment the EIGRP is used.
The commands are shown below:
Fig 12: EIGRP Configuration in Router0
The EIGRP syntax starts with ‘router’ followed by ‘eigrp’ and an autonomous number
that can be anything between 1 to 65536. This number should be same on all the routers to
discover its neighbour routers. After that enter all the network addresses that are connected
directly to the respective router. Then enter Ctrl+Z to save the configuration. Follow the same
procedure for other routers as well.
