Thank you, Sensitivity Label: General From: Job Snijders <[email protected]> Date: Tuesday, 4 August 2026 at 16:43 To: [email protected] <[email protected]>; [email protected] <[email protected]> Subject: A well-known DOWNGRADE BGP Community Dear all, Following up on a recent NANOG thread on RTBH [1], [2]; we'd like to put forward an different strategy for DoS attack mitigation. Perhaps just as an extra tool in the toolbox? Abstract -- This document outlines a method to mitigate Denial of Service (DoS) attacks by using a well-known BGP community named "DOWNGRADE" as signal to neighboring networks to treat traffic destined towards "DOWNGRADE" tagged IP prefixes with low precedence. The "downgrade" strategy offers an appealing alternative to Remote Triggered Blackhole (RTBH) filtering, because RTBH filtering completes the DoS attack and hampers the defender's ability to monitor whether the attack is still ongoing.
