HSRP vs VRRP vs GLBP vs CARP + Cloud HA | First Hop Redundancy Explained Redundancy isn’t optional — it’s essential. In this Technically U episode, we go beyond the basics and dive deep into the world of first-hop redundancy protocols, comparing:✅ HSRP (Cisco’s classic standby setup)✅ VRRP (the open standard failover protocol)✅ GLBP (Cisco’s answer to load-balanced gateway redundancy)✅ CARP (an open-source hero used in pfSense and BSD systems)✅ Cloud & SD-WAN HA (modern, policy-driven high availability in the cloud)🎧 You’ll learn:What each protocol does and how it worksBenefits and limitations of each solutionDifferences in vendor support, authentication, and scalabilityHow to choose the right option for Cisco, open-source, multi-vendor, or cloud-native networksWhy cloud networks no longer rely on traditional gateway protocolsWhether you're designing a bulletproof LAN or deploying in the cloud, this episode helps you make smarter network architecture decisions.📲 Like, comment, and subscribe for more real-world tech insights every week.
