In BGP an AS could announce paths for arbitrary IP addresses, resulting in false routings. Is there a mechanism that prevents such actions?

    Not only is this possible, there are well-known cases in the relatively recent past. – Daniel B Aug 10 '21 at 12:07
  • There's no such mechanism, moreover, there were multiple attacks based on exactly this behavior. – raj Aug 10 '21 at 13:29
