BGP and RPKI Explained: Why Origin Is Not the Whole Path

A 15-minute Brainmetry engineering documentary on internet routing and route origin validation. BGP reachability, AS paths, policy, longest-prefix forwarding, ROAs, validators, Valid/Invalid/NotFound, maximum prefix length and route leaks. Origin-valid is a specific authorization result, not a guarantee that the whole path is legitimate. Simplified animated diagrams; fictional network examples. The June 27, 2024 incident is attributed to Cloudflare's report, with no claim about external networks' intent. No current adoption percentage or universal security guarantee.
