BGP ORIGIN attribute manipulation and its impact on the Internet

Cloudflare's investigation into BGP ORIGIN attribute manipulation reveals a significant issue where ~70% of observed paths have altered ORIGIN values compared to the originating Autonomous System. This manipulation influences traffic forwarding on the Internet, with the ORIGIN attribute determining route selection in case of equal Local Preference and AS_PATH length. Network operators rewrite the ORIGIN attribute to IGP for revenue-driven purposes, driving traffic to their links and creating an inconsistent handling of ORIGIN across the Internet.
