IDR Working Group C. Loibl, Ed. Internet-Draft next layer Telekom GmbH Updates: I-D.ietf-idr-rfc5575bis (if R. Raszuk, Ed. approved) Bloomberg LP Intended status: Standards Track S. Hares, Ed. Expires: May 20, 2021 Huawei November 16, 2020 Dissemination of Flow Specification Rules for IPv6 draft-ietf-idr-flow-spec-v6-20 Abstract Dissemination of Flow Specification Rules I-D.ietf-idr-rfc5575bis provides a Border Gateway Protocol extension for the propagation of traffic flow information for the purpose of rate limiting or filtering IPv4 protocol data packets. This document extends I-D.ietf-idr-rfc5575bis with IPv6 functionality. It also updates I-D.ietf-idr-rfc5575bis by changing the IANA Flow Spec Component Types registry.
