ICTNWK506: Configuring, Verifying, and Troubleshooting WAN Links

This document presents a comprehensive solution for the ICTNWK506 assignment, focusing on configuring, verifying, and troubleshooting WAN links and IP services within a medium enterprise network. The assignment covers practical tasks such as preparing and installing WAN links using serial connections and copper cables, and includes testing network configurations using Cisco Packet Tracer. It also addresses the configuration and verification of WAN links, including network configurations, ADSL connections, and their advantages and disadvantages compared to cable broadband technologies. Furthermore, the solution encompasses site-to-site VPN configurations using IPSec VPN tunnels, and the implementation of DHCP, NAT, and ACL configurations, including IPv6 and troubleshooting WAN issues. The document provides access control list examples and discusses mitigation strategies for network configuration challenges, along with a bibliography of relevant sources. This assignment is designed to provide students with the practical skills needed to manage and troubleshoot WAN environments.

Assessment Task 1: Practical Tasks
Task 1: Prepare and Install Medium Enterprise WAN links
For the installation of the Medium enterprise WAN link serial connection should be used for
interconnecting the routers with each other and copper straight through cable is used for the
management of the distribution of the network. The prototype of the network is created in
cisco packet tracer and it is tested for checking the connection between the devices and
eliminating the errors in the configuration.
Task 2: OHS and test report
The simulation option is started and packets are sent from different devices in the network for
testing the configuration of the network. The take for the data packet to reach the destination
location is noted with the path selected for the transmission.
Assessment Task 2: Configuration and verification of WAN Links
Task 1: Network Configuration
PC 1 to PC 2 Ping test

PC 2 to PC 1 Ping test
PC 2 to PC 1 Trace route

Task 2: ADSL Connections
ADSL –
Advantages
It helps in transmission of the voice and data packets in separate bands using separate
communication channels. It can be applied in the existing infrastructure without incurring
extra cost and time.
Disadvantages
The performance of the DSL connection is dependent on the distance of the telephone
exchange

ICTNWK506
The service may not be available in remote location.
Cable broadband technologies –
Advantages
It is available in most off the remote location and it uses the same lines for the television and
the data packets.
Multiple user can work simultaneously at the same time and it uses highly reliable connection
Disadvantages
It cost more that the dial up connection and the cost can be reduced if a separate phone line is
used
The speed of the network cannot be guaranteed because it is dependent on the IPS server.
Assessment Task 3: Site to Site VPN
IPSec VPN Tunnel – it is used for encapsulation of the data packet and an IP header is added
to the original packet and sent to the other side of the VPN tunnel.
Assessment Task 4: DHCP, NAT and ACL configurations
Task 1: DHCP and NAT

Task 4: WAN issues
There are different problems faced during the configuration of the network and it should be
mitigated for the development of the network framework. Different internet blogs and cisco
sites are visited for the analysis of the protocols that are needed for the configuration of the
routers. The links that are given in the document are verified for the WAN links and
resolving the connectivity issues. The different layers of the network and the address table of

the router is analysed for the configuration of the access control list. The skills and
knowledge can act as a barrier for the development of the network solution and it should be
improved for the development of the network framework.
