The Network Design Assignment considers the organization requirements and prepares a network design to suit the requirements outlined in this report.

1. Network Design Assignment
1. Requirement and Project Scope
1.1 Requirements
This Network Design Assignment considers the organization requirements and prepares a
network design to suit these requirements. In addition to designing this report also focuses on
developing a network configuration which involves configuration of routers and switches. This
is followed by access point detailing and configuration of the server finalization. Post which an
estimated budget is prepared for implementation of this network design.
1.2 Scope
In the next step the project prepares the complete network configuration based on network
design prepared. As per this design IPv6 configuration will be provided to the branches A and B
while IPv4 configuration will be provided to branch C. IPv6 configuration will also be applicable
for headquarter branch. There is no flexibility to project budget, and it needs to be completed
within this approval limit. Also, there can be no extension to the project timelines as this will
result in expenses to resources. Hence increasing the budget.

2.4 Choice Justification
For good effectiveness and efficiency of the network design, the routing protocol selected is
Open Shortest Path First (OSPF) because it has various benefits to a network design. Starting
with being a loop free protocol the time required for transferring changes to the entire
autonomous system in the router is very minimum which improves the performance of the
network. In addition to this benefit network overhead is also reduced by this protocol which
means less interference for the network and hence effectiveness is better. The network security
is also improved by this protocol as MD5 authentication is carried along with implementation of
interface based plain text. This capability of the OSPF routing protocol ensures that it can
handle a large scale of networks up to thousand units.
Due to a dual stack mechanism being applied in this network design which consists of IPv4 and
IPv6 for different branches, the efficiency is improved. Both the branches A and B can easily
communicate among themselves while branch C follows a different protocol IPv4. The dual
mechanism context of IPv4 and IPv6 protocol has already been discussed earlier in the report.

10. 3.4 Host Configuration
Branch C PC Configuration
3.5 Guidelines for server configuration and access point.
Below steps are required to configure the access point:
 Deployment of switches and the routers to be done.
 For connection of the router to the computer and router to the access point, Ethernet
cable is to be used.
 Configuration of access point is done by entering a default IP address in the access point
webpage.
Below steps provided in this Network Design Assignment are required for the configuration of
the server:
 Configuration of IP address is done.
 Configuration of DNS name server is done.
 Configuration of host name is done
 Validations of domain settings is to be done.

11.  Configuration of TLS or transport layer security is done and then server configuration is
completed by enabling sub domain isolation.

Conclusion
Network design details and its implementation procedures have been illustrated in this
Network Design Assignment for the given organization. Network configuration and device
requirements have also been detailed. Owing to its various benefits, Open Shortest Path First
(OSPF) has been selected for the network design. In order to maintain an effective and efficient
communication network, the dual stack mechanism of IPv4 and IPv6 has been considered for all
the three branches and the headquarters. Cost estimation has also been prepared considering
the optimal number of resources required for the project completion. Considering the cost of
team members, Consultant and the Project Manager the budget estimates is between $105,000
and $160,000. In addition, the timelines for project completion has also been estimated for this
project and this comes out to an approximate of 63 days. The timeline estimate includes
completion of all the activities which are part of this project and maintain the quality delivered

14. for each of the activities so that the objective of maintaining a high effectiveness and efficient
network design is achieved.
