This paper presents the steps of how to make the network reliable by usingRedundancy scheme and how to balance traffic load in order to reach optimal network.The implemented network is based on IEEE 802 LAN standard in which the equipmentused in the topology is 3745Cisco’s routers module and 2960 Ether Switch.Also the Hot Standby Redundancy Protocol (HSRP), Gateway Load Balancing Protocol(GLBP), and Virtual Redundancy Routing Protocol (VRRP) are implemented in thiswork. Many tests in this work in order to achieve the load balancing of the implementedprotocols (test the redundancy scheme) and to test the network performance throughCPU utilization, bandwidth consumption by protocols, and measure the convergencetime of the implemented protocols in the network. This paper gives a guideline forInternet Service Provider’s Network (ISP) in order to avoid loss of information andincrease the productivity and revenue. The obtained results show that the GLBP has thebest performance in terms of CPU utilization and convergence time, and also in linkconsumption in comparison with HSRP and VRRP protocols for the same conditions.
