BGP Zombies - Ghost Routes as Seen by BGP Monitoring Platforms

Watch a 25-minute NANOG conference talk exploring the phenomenon of "BGP zombies" - persistent routing table entries that remain active despite being withdrawn. Learn how these ghost routes impact Internet routing systems through research findings from both RIPE RIS and Code BGP monitoring platforms. Discover key insights about which Autonomous Systems and prefix types are most susceptible to zombie occurrences, and understand why BGP zombies persist regardless of monitoring platform or prefix announcement characteristics. Gain valuable knowledge about the importance of developing mechanisms for identifying, labeling and alerting users to BGP zombies to help maintain network stability and performance. Presented by Lefteris Manassakis, network engineer turned researcher and co-founder/COO of Code BGP, who shares his expertise on this pervasive routing challenge.
