See the "BGP Announcements" card on any AS page. Example: https://radar.cloudflare.com/routing/AS13335

I fail to reproduce the same numbers with my own tool when I use a single location from routeviews MRT dumps.

Do they count any of the 8 possible subtypes as 1 annoucement? Do they count one annoucement per prefix in a single UPDATE message?

Their documentation fails to precise this.

  • I use the 20231024.1600 RIB dumps, and also included any updates file in the 16:00-17:59 time range.
