BGP Role model: tracking the adoption of RFC 9234
RFC 9234 lets routers reject route leaks on their own, using BGP Roles and the Only to Customer attribute. We measured who has deployed it, and found two Tier 1 networks unexpectedly stripping OTC.

RFC 9234 lets routers reject route leaks on their own, using BGP Roles and the Only to Customer attribute. We measured who has deployed it, and found two Tier 1 networks unexpectedly stripping OTC.
By doing in-depth testing, we found nearly 70% of BGP paths experience ORIGIN attribute rewrites by transit providers seeking traffic advantages. We examine the global impact of this practice and argue for deprecating ORIGIN in route selection.
BGP is vulnerable to routing hijacks and path leaks that negatively impact traffic on the Internet. RPKI helps solve some of these problems, but for some forged paths, we need to rely on a simpler mechanism: First AS enforcement in BGP.
ASPA is the cryptographic upgrade for BGP that helps prevent route leaks by verifying the path network traffic takes. New features in Cloudflare Radar make tracking its adoption easy.
There has been speculation about the cause of a BGP anomaly observed in Venezuela on January 2. We take a look at BGP route leaks, and dive into what the data suggests caused the anomaly in question.
We present a data-driven framework to quantify cross-layer Internet resilience. We also share a list of measurements with which to quantify facets of Internet resilience for geographical areas.
On September 3, 2024, the White House published a report on Internet routing security. We’ll talk about what that means and how you can help.
Is BGP safe yet? If the question needs asking, then it isn't. But how far the Internet is from this goal is what we set out to answer.
In this blog post, we will introduce our new system designed to detect route leaks and its integration on Cloudflare Radar and its public API.
