I am using bgpreader as

bgpreader -A "20940" -w 2023-7-28,2023-7-31

where ASN 20940 is Akamai (a CDN). I wanted to view RIB, updates involving this ASN. I couldn't find the result for other CDN ASNs (eg. ASN 12200- Rackspace, 16509-Amazon). I can view results when I use any ASN instead of CDNs there.

  • I've never used this tool myself, but looking at the documentation I'd expect to use -a (matching origin ASN) instead of -A (as-path).
