Source-IP-Origin-AS Filter for BGP Flow Specification

groupnone stateactive pages9 rev01 expires2026-09-20 canonicalhttps://datatracker.ietf.org/doc/draft-wang-idr-flowspec-sip-origin-as-filter/

This document defines an extension to the Border Gateway Protocol (BGP) Flow Specification (FlowSpec) to enable filtering based on the Origin Autonomous System (AS) of the source IP address. This extension is particularly useful in mitigating Distributed Denial of Service (DDoS) attacks where the source IP addresses are dynamic but belong to a specific source AS.
