BGP flow specification version 1 (FSv1), defined in RFC 8955, RFC 8956, and RFC 9117 describes the distribution of traffic filter policy (traffic filters and actions) distributed via BGP. During the deployment of BGP FSv1 a number of issues were detected, so version 2 of the BGP flow specification (FSv2) protocol addresses these features. In order to provide a clear demarcation between FSv1 and FSv2, a different NLRI encapsulates FSv2. IDR requires two implementations prior to standardization. Implementers feedback on FSv2 was that the complete FSv2 has the contains the correct information, but that breaking FSv2 into a progression of documents would be helpful. The first priority in this progression is expanded IP DDOS capabilities. This document contains original FSv2 IP DDOS capabilities in FlowSpec v2 using just the extended communities to define actions.
