BGP Role model: tracking the adoption of RFC 9234
RFC 9234 enables routers to autonomously prevent route leaks by utilizing BGP Roles and the Only to Customer attribute, with observations revealing unexpected behavior from two Tier 1 networks stripping the OTC attribute.
MAIN POINTS
- RFC 9234 allows routers to independently reject route leaks.
- It uses BGP Roles and the Only to Customer (OTC) attribute.
- Deployment measurements were conducted to assess adoption.
- Two Tier 1 networks were found stripping the OTC attribute unexpectedly.
TAKEAWAYS
- RFC 9234 enhances network security by preventing route leaks.
- BGP Roles and OTC attribute are central to RFC 9234's functionality.
- Adoption of RFC 9234 is being actively measured in the industry.
- Unexpected stripping of OTC by Tier 1 networks indicates potential implementation issues.
