## BGP real-time routes

Cloudflare Radar's prefix routing page displays real-time BGP routes as a [Sankey diagram][sankey]. This visualization is built using MRT data from [RouteViews][route-views] and [RIPE RIS][ripe-ris], combined with real-time streams from RouteViews' Kafka instance and [RIS Live][ris-live].

By default, the route visualization shows paths from the originating AS to [Tier-1 networks][tier-1], omitting the segments from Tier-1 networks to BGP route collectors for clarity. Users can choose to see the complete paths using the "Show full paths" toggle.

Above the visualization, a table details the prefix origin, including the originating AS, its visibility percentage across route collectors, and [RPKI][rpki] validation status (`valid`, `invalid`, `unknown`).

Hovering over a link in the diagram reveals a tooltip with the connected ASNs, the observing BGP route collectors (from [RIPE RIS][ris-collectors] and [RouteViews][route-views-collectors]), and the last update timestamp.
