If you run BGP in production and you're not validating route origins with RPKI, you're accepting every prefix announcement on trust alone. That's the equivalent of letting anyone walk into your data center and plug into a switch because they said they work there. BGP RPKI Route Origin Validation (ROV) is the mechanism that changes this. With 500K+ ROAs published globally, mature validator software, and RFC 9774 formally deprecating AS_SET, there's no technical barrier left. Here's how to deploy it on Cisco IOS-XE and IOS XR. How RPKI ROV Actually Works RPKI (Resource Public Key Infrastructure) cryptographically binds IP prefixes to the autonomous systems authorized to originate them. Three components make it work: Route Origin Authorizations (ROAs) — Signed objects published by prefix holders in RPKI repositories. A ROA states: "AS 65001 is authorized to originate 192.0.2.0/24 with a maximum prefix length of /24." RPKI Validators — Servers (Routinator, Fort, OctoRPKI) that download ROA
