Gateway Redundancy with FHRP provides a clear, practical introduction to the three major First Hop Redundancy Protocols—HSRP, VRRP, and GLBP—and how they ensure resilient default-gateway availability in enterprise networks. Through structured explanations and configuration-focused examples, the course explores each protocol’s purpose, election processes, state machines, timers, authentication options, load-sharing capabilities, and failure-detection mechanisms. You’ll learn how these redundancy protocols operate, how to implement them on Cisco devices, how features like object tracking and preemption influence failover behavior, and how to verify proper functionality using real IOS commands. This course delivers the essential knowledge needed to design, configure, and troubleshoot reliable gateway redundancy in modern Layer-3 campus environments.
