HSRP vs VRRP vs GLBP - Welcome to the World of Gateway Redundancy
Description
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 works
Benefits and limitations of each solution
Differences in vendor support, authentication, and scalability
How to choose the right option for Cisco, open-source, multi-vendor, or cloud-native networks
Why cloud networks no longer rely on traditional gateway protocols
Whether you're designing a bulletproof LAN or deploying in the cloud, this episode helps you make smarter network architecture decisions.
