IP Anycast BGP Routing, Failover & Path Manipulation Demo
Dive into a full end‑to‑end demonstration of IP Anycast using a lab setup with 2 servers, 4 autonomous system routers, and BGP to tie it all together.
In this video, I show how Anycast routing works in practice — from clients automatically reaching the closest server, to seamless failover when a node goes offline, to manipulating BGP path selection to steer traffic toward the preferred destination.
You’ll see:
• How Anycast addressing is configured and advertised
• How two clients choose their nearest server using BGP
• What happens during a server or path failure
• How to influence routing decisions using BGP attributes
• Why Anycast is used for DNS, CDNs, DDoS mitigation, and global services
Whether you’re studying networking, building distributed systems, or just curious about how the internet makes smart routing decisions, this walkthrough gives you a clear, practical look at Anycast in action.
