Southern Cross University CSC73002 Network Configuration Report

This report, prepared for the CSC73002 Network Management unit at Southern Cross University, details the configuration and management of a simulated enterprise network comprising a headquarters and two branches connected via the internet. The report begins by presenting the physical network topology, including the layout of workstations and network equipment, and specifies suitable hardware configurations for routers and switches. It then outlines the configuration of network devices, including port settings and linking technologies, and discusses the implementation of RIP routing, validated with packet captures in Wireshark and internetwork routing verification via ping tests. The report also revisits the network design, addresses hardware and software requirements, reviews current device configurations, and explores change management strategies. The report concludes with a summary of the findings and includes a bibliography of cited sources.

MANAGEMENT AND VALIDATION OF NETWORK
Summary
It has been proved by a vast number of researches that the physical layout of network, the
underlying interfaces as well as the routing protocol for configuring networks are what
determines the effectiveness and efficiency of the network. The report investigates one such
network on the above mentioned grounds. First this report presents and discusses the physical
networking topology and highlights the specific details. Then it provides the suitable
configuration for the various network equipment like routers and switches, specifically their
port configurations and talks about the suitable linking technologies. Then the correct
configuration of individual devices are discussed along with the interfaces used by them.
Next the report shows the configuration of RIP routing and validates it with packet capture in
Wireshark along with validation of the internetwork routing by pinging devices of the
different networks. The report now revisits the network and also talks about the design
aspect, after which the hardware and software requirements are given. Then after showing the
current running state of devices the report touches change management of the network is
touched and then the report ends with conclusions.

MANAGEMENT AND VALIDATION OF NETWORK
Introduction
This report highlights the role that the physical layout of network, the underlying
interfaces as well as the routing protocol for configuring networks play in determining the
effectiveness and efficiency of the network. The report investigates one such network on the
above mentioned grounds. The report begins by presenting and discusses the physical
networking topology and highlights the specific details. Then it provides the suitable
configuration for the various network equipment like routers and switches, specifically their
port configurations and talks about the suitable linking technologies. Then the correct
configuration of individual devices are discussed along with the interfaces used by them.
Next the report shows the configuration of RIP routing and validates it with packet capture in
Wireshark along with validation of the internetwork routing by pinging devices of the
different networks. The report now revisits the network and also talks about the design
aspect, after which the hardware and software requirements are given. Then after showing the
current running state of devices the report touches change management of the network is
touched and then the report ends with conclusions.

Task 1: Network Simulation
Physical Network Topology
Figure 1: Physical network topology Diagram
The diagram above contains the network’s physical topology as it shows the physical
layout of the workstations and network equipment involved for the network segments of the
headquarters and of both branch A and branch B. The two branches and the headquarters are
interconnected over the internet by means of the ISP. The IP networks used for the
headquarters, branch A and branch B are 192.168.10.0, 192.168.11.0 and 192.168.12.0
respectively. The interfaces used by the ISP router for connecting switches of these different
network segments happens to be GE 0/0/0, 0/0/1 and 2/0/0 and are received by the GE 0/0/1
interface of each of the switches belonging to the headquarters and branches A and B
respectively. The PCs or workstations get connected to the layer 2 switches of these network
segments through their Ethernet 0/0/1 interface. Thus the overall network representing the
different labs of the university is formed by the above network.

MANAGEMENT AND VALIDATION OF NETWORK
Suitable link technologies
As can be observed from the routing table in the above screenshot, connections to
specific switches for the headquarters and that of the two branches from the router of the ISP
is facilitated via the use of GigabitEthernet or the GE interfaces.
Correct physical topology with sufficient notation
The physical networking topology diagram as also the screenshot of the routing table clearly
elaborates the physical interfaces and ports that are being used by the respective switches and
routers for facilitating network access for the PCs and workstations that the particular
network segment is to serve. The topology diagram also mentions the IP networks that is
192.168.10.0, 192.168.11.0 and 192.168.12.0 which are being used by the router to route the
network for the respective segments.

MANAGEMENT AND VALIDATION OF NETWORK
Device configuration
Device administration configuration
The network address, IP address and default gateway configurations are specified in
this ‘Basic Config’ tab of client PCs when opening the settings for each device. That these
devices have IP addresses assigned through static IP allocation mode is clearly visible from
the above screenshot. Specifying the IP of the router for the respective interface as the default
gateway of these devices makes it possible for these devices to communicate with one
another through the router.

MANAGEMENT AND VALIDATION OF NETWORK
Correct interface configuration
In this screenshot above the routing table displays the configuration of various
interfaces used for connecting the different devices present in the network. The router of the
ISP uses these interfaces and the mentioned IP configuration for providing network access to
the client PCs of the headquarters and the two branches A and B.

MANAGEMENT AND VALIDATION OF NETWORK
Internetwork routing configuration
RIP routing configuration
This screenshot displays the inclusion of the three required networks for the network
segments of the headquarters, branch A and branch B in the version 1 instance of RIP as it
gets configured on the ISP router.

11
MANAGEMENT AND VALIDATION OF NETWORK
In this screenshot the packet capture of network communications through the interface
Ethernet 0/0/1 of the device is shown. It is clearly visible that the router with IP 192.168.11.1
for the interface of branch A is using the RIP version 1 instance to facilitate the network
connection between the device and the router.
