The main objective of this study is the empirical analysis of the evaluation and comparison of dynamic routing protocols regarding their stability and reliability. An especially close look will be paid to EIGRP, OSPF, and RIP; RIP (Routing Information Protocol) being one of the oldest routing protocols still in service.
A routing protocol is a protocol which is responsible to determine how routers communicate with each other and forward packets through an optimal path, travelling from source node to destination node. Each routing protocols performs in different ways. They have their own architecture, route to follow and sometimes even delays in packets. OSPF builds a database of routes to its neighbors, using an algorithm to calculate the best possible path. EIGRP is a vector routing protocol that is used on a computer network to help automate routing decisions and configuration.

Research Objectives and Themes
The primary aim of this work is to conduct an empirical analysis on the evaluation and comparison of dynamic routing protocols—specifically RIP, EIGRP, and OSPF—to determine their effectiveness regarding network stability, reliability, convergence speed, and performance under varying topological conditions using the Cisco Packet Tracer simulation tool.
- Comparative performance analysis of RIP, EIGRP, and OSPF routing protocols.
- Evaluation of network convergence times during link failures or router shutdowns.
- Analysis of end-to-end packet delay and destination unreachable metrics.
- Investigation of protocol efficiency in large-scale vs. small-scale network topologies.
- Assessment of the scalability and routing table maintenance behavior of each protocol.
Excerpt from the Book
A. Routing Information Protocol(RIP)
As discussed in review parts, RIP is a standardized vector distance routing protocol and uses a form of distance as hop count metric. RIP is also known as a distance vector. RIP prevents routing loops, by limiting the number of hop counts allowed in paths between sources and destinations. Basically, the maximum number of hops allowed for RIP is 15. However, by achieving the routing loop prevention, the size of supporting networks is sacrificed. Because of the maximum number of hop counts allowed for RIP is 15, as long as the number goes beyond 15, the route would be considered as unreachable.
When first developed, RIP only transmitted full updates every 30 seconds. In the early distributions, traffic was not important because the routing tables were small enough. As networks become larger, massive traffic burst becomes more likely during the 30 seconds period, even if the routers had been initialized at different times. Because of this random initialization, it is commonly understood that the routing updates would spread out in time, but that is not the case in real practice.

How does OSPF perform compared to RIP and EIGRP according to the findings?
The simulation results demonstrate that OSPF generally provides faster convergence and greater reliability than RIP and EIGRP, making it preferable for large enterprise networks with many routers and frequent topology changes.
How does EIGRP distinguish itself from the other protocols?
EIGRP is categorized as a hybrid protocol that uses the Diffusing Update Algorithm (DUAL) for fast convergence and triggered updates, which significantly reduces the routing protocol load compared to the periodic updates used by RIP.
