Comparative Study of EIGRP and OSPF Protocols based on Network Convergence

Abstract

Dynamic routing protocols are one of the fastest growing routing protocols in networking technologies because of their characteristics such as high throughput, flexibility, low overhead, scalability, easy configuration, bandwidth, and CPU utilization. Albeit convergence time is a critical problem in any of these routing protocols. Convergence time describes summary of the updated, complete, and accurate information of the network. Several studies have investigated EIGRP and OSPF on the internet; however, only a few of these studies have considered link failure and addition of new links using different network scenarios. This research contributes to this area. This comparative study uses a network simulator GNS3 to simulate different network topologies. The results are validated using Cisco hardware equipment in the laboratory. The network topology implemented in this research are star and mesh topology. The results are validated using Cisco hardware equipment in the laboratory. Wireshark is effectively used in capturing and analyzing the packets in the networks. This helps in monitoring accurate time response for the various packets. The results obtained from Wireshark suggest the EIGRP has a higher performance in terms of convergence duration with a link failure or new link added to the network than the OSPF routing protocol. Following this study EIGRP is recommended for most heterogeneous network implementations over OSPF routing protocol.

[Retracted] Design Analysis of Intelligent Enterprise Costing Platform Based on a Virtual Network Mapping Algorithm

“…Figure 2 illustrates how network virtualization uses mapping algorithms to optimally allocate virtual resources across the physical infrastructure. Virtual network operators use mapping algorithms to decide to request certain virtual resources from the VNP, which are then instantiated by the underlying InPs [16]. Virtual network mapping allocates virtual resources to nodes and links and can be divided into two subproblems: virtual node mapping, i.e., mapping all virtual nodes to the corresponding physical nodes, and virtual link mapping, i.e., mapping the virtual links connecting virtual nodes to the physical links connecting physical nodes accordingly.…”

Strategic Framework for Campus Network Environment Using Virtual Switching System

“…When the waiting period exceeds beyond 10 seconds the standby router takes up the active job of packet transfer. Here, the priority of the active router is removed due to router failure and standby router's priority becomes the highest in the HSRP group [9]. During this switch over, nearly 2-3 packet loss was observed.…”

“…Apart from this, to have better flexibility in the network, implementation of dynamic routing protocols is necessary for increasing throughput, bandwidth, scalability that reduces the CPU utilization and convergence time. Okonkwo and Emmanuel, (2020) [9] made a comparative study between EIGRP and OSPF by implementing star and mesh network topology. The experiment showed that EIGRP gave higher performance for checking the link failure and adding new links as per the network requirement.…”

“…This is made possible by implementing VSS in the distribution and core layer using the L3 switch that forms a 3-Tier architecture in a campus design. To support higher convergence Enhanced Interior Gateway Routing Protocol (EIGRP) routing is used to increase the throughput and manage the routing peers dynamically [9]. Even Multi-chassis Ether Channel (MCE) is incorporated to discard the dependency of STP protocol, thereby providing dual-link for load balancing the VLANs and supporting loop-free topology.…”

Performance Comparison of OSPFV3 and EIGRP with IPv6 Network

“…VLSMs allow you to granularly assign essential bits of the host. The main characteristic of the routing protocol is its unequal load balancing [26]. The routing protocol of EIGRPv6 has 3 tables that aid in routing decisions [27].…”
