Eastlake 3rd and Jie Dong and Chaitanya Yadlapalli and Sven Maduschke and Jeff Haas}, title = {{BGP Flow Specification Version 2 - for Basic IP}}, pagetotal = 54, year = 2026, month = may, day = 9, abstract = {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 issues. In order to provide a clear demarcation between FSv1 and FSv2, a different NLRI encapsulates FSv2. The IDR WG requires two implementation. Early feedback on implementations of FSv2 indicate that FSv2 has a correct design direction, but that breaking FSv2 into a progression of documents would aid deployment of the draft (basic, adding more filters, and adding more actions). This document specifies the basic FSv2 NLRI with user ordering of filters added to FSv1 IP Filters and FSv2 actions.}, }
