ABSTRACT

After years of development and improvement, network based on IPv4 (Internet Protocol

version 4) has proven to be a mature technology, easy to implement and has a good

network protocol interoperability. One can say that it has achieved great success.

However, with the rapid development of new Internet services and the emergence of new

business, there are shortcomings in the current IPv4, such as the lack of address space,

the rapid expansion of the routing table, the lack of mobile network quality of service and

support for a range of issues. 32 bit IPv4 address i.e. up to 2 32

addresses can be divided

into about 4.3 billion devices. By the end of 2012, there will be 6.2 billion of population

so there is a need to migrate from this IPv4 version to IPv6.

To meet the future growth in the Telecommunications and Internet space, National

Institute of Technology, Hamirpur (HP) being a constituent of ministry of HRD,

Department of Higher Education, Govt. of India is also required to implement IPv6 at

NIT Hamirpur

In this project, we present some mechanisms that have been implemented to ease this

transition especially for IPv4 users that still want to communicate with their old

applications. We have set up a test bench on an IPv4 to IPv6 tunneling and dual stack

mechanism on CISCO routers and switches that transparently establish a hybrid

communications between the two worlds in both ways and have some advantages over

the other models. We also implement a mechanism to implement an ipv6 tunneling oven

ipv4 network that will be efficient on a large scale. After doing the case study of NIT

Hamirpur campus network, we also propose a migration plan of the campus network

from IPv4 to IPv6.

INTRODUCTION

In the early 1990s it became apparent that the 32-bit address size of the IPv4 protocol

would be too small in the long run, so the Internet Engineering Task Force (IETF) started

work on an updated version of IP with larger addresses, IPv6. Unfortunately, the resulting

protocol is not backward compatible with IPv4, so there is a need for tools to allow the

transition from IPv4 to IPv6 and the coexistence of the two protocols

The purpose of the project is to study the existing transition techniques that are used for

communication between two network having different internet protocols IPv4 and IPv6

and then create a test bench having the best techniques implemented on the various

network devices. We have studied the three techniques used for IPV4 to IPv6 transition

tunneling, dual stack and NAT PT.

We have created a small test bench consisting of three CISCO 2800 routers with one

router working on IPv4 and other two on dual stack, two CATALYST switches both on

dual stack and two end hosts. After studying all the tunneling methods, we have

implemented IPV4 to IPv6 tunnel to establish the end to end communications between

the two end hosts.

We have also mentioned a tunneling technique called IPv6 over IPv4 for the bigger

networks. After doing the case study of NIT Hamirpur network, we have examined the

necessary changes needed to migrate NIT-Hamirpur network from IPv4 to IPv6.

OBJECTIVES

The project has the following objectives:

To study the router and switch configurations.

To study about the various IPv4 to IPv6 transition mechanisms.

To create a test bench having IPv4 and IPv6 network and to establish a

communication between the two networks.

To study the network of NIT-Hamirpur and propose the modification needed to

migrate the network to IPv6.
