AbstractThe expanding need of computers is growing rapidly in modern civilization and subsequently theneed of computer networks. The developing need of high-performance and high-capacity internetacross wide area of campus which is intermediately connected through each other requires the use of switching nodes and routers. The aim of this research is to design and implement using dynamic routing protocols with secure integration which will primarily focus on protocols EIGRP and OSPF. Both of these protocols have been designed and implemented by Cisco and are generally used for a wide range of area. The protocol EIGRP was an enhancement to IGRP and iBGP protocols due to some limitations of these protocols. The other protocol to design and discuss is OSPF which has been designed in order to make changes in an already existed network setup when user doesn’t want much changes to the existing network and no changes in the WAN routing at all. OSPF is the solution to this problem.Hence this report discusses about both of these routing protocols in details regarding their design, literature review and implementation.

Chapter 11. IntroductionAn important issue to any kind of network system is the security. To prevent all kind of network threats is a challenging task for the network administrators as sometimes the area, use of networkand complexity can be really vast in size which is difficult to manage[ CITATION AKu14 \l 1033 ]1. To handle this issue there are multiple protocols that are used by the network professionals to ease the task and handle the security issues in more complicated systems. These protocols are divided into distance routing protocols, dynamic routing protocols and many other[ CITATION VSh12 \l 1033 ]2.Dynamic routing protocols have lots of advantage over distance vector routing protocols. Virtually there is no hop count limit to these kinds of protocols[ CITATION DPe03 \l 1033 ]3. Comparing distance vector routing protocols to dynamic routing protocols shows that, latter provides valid authentication of the network user while former doesn’t[ CITATION ESL10 \l 1033 ]4. A dynamic routing protocol controls traffic and balances the load on the network convergence is also faster as compared to others. The two protocols of dynamic routing that are responsible for rapid convergence of data from sender to the receiver are EIGRP (Enhanced Interior Gateway Routing Protocol) and OSPF (Open shortest Path First)[ CITATION VSh12 \l 1033 ]2. These two protocols are able to support transmission of multi-access topology for example Ethernet and Token-Ring. This report will describe in detail the design and implementation of these two protocols and the way they help in constructing a secured and integrated network.1.1 Problem DescriptionWhen Cisco was in rapid phase of their growth during late 90s their IT team evaluated that there is a need of different routing protocol which makes scaling easier[ CITATION Nar09 \l 1033 ]5.At that point of time IGRP and iBGP protocols were used within regions and between regions respectively. Cornell, IT architect for Cisco Network Services quoted that “Every time they expand their network to some new area, they have to change a lot to the existing network
