BGP Role model: tracking the adoption of RFC 9234

This post details the analysis of RFC 9234 (BGP Roles and OTC attribute) adoption across the internet. It explains how BGP Roles and the OTC attribute work to prevent route leaks and describes Cloudflare's methodology for tracking adoption by monitoring OTC attribute propagation from peer ASes. The analysis reveals that while adoption is growing, two major Tier-1 networks are stripping the OTC attribute, which is a significant impediment to widespread route leak prevention. The post also provides guidance on how to enable BGP Roles in one's own network.
