Summary

Cloudflare measured deployment of RFC 9234, which lets routers reject route leaks using BGP Roles and the Only to Customer attribute, and found two Tier 1 networks stripping OTC.

Key facts

  • RFC 9234 enables routers to reject route leaks on their own.
  • It uses BGP Roles and the Only to Customer attribute.
  • Cloudflare measured which networks have deployed RFC 9234.
  • Two Tier 1 networks were found stripping OTC.

Why it matters

Networks relying on RFC 9234 for leak protection may find it ineffective where Tier 1 providers strip the OTC attribute, so operators should verify behavior along their paths.
