Abstract
High level of availability can be expensive to maintain, but lack of availability may also increase cost as it may damage the reputation of the business. Which led to the development of techniques that reduce downtime until it became transparent to the user. The first hop redundancy protocols are protocols used to manage and maintain network default gateway router by using one or more redundant routers that will take over in case of default router failure. The First Hop Redundancy Protocols (HSRP, VRRP, and GLBP) will be implemented, tested, optimized, and compared to one another in terms of convergence time, packet loss and CPU utilization, by using GNS3 simulator and Wireshark the results of comparison will be provided and analyzed. The comparison indicates that which protocol is best in which scenario and which is best among the three protocols.
