Nokia Arrcus Huawei Technologies This document defines a new extended community known as "FlowSpec Redirect to indirection-id Extended Community". This extended community triggers advanced redirection capabilities to flowspec clients. When activated, this flowspec extended community is used by a flowspec client to retrieve the corresponding next-hop and encoding information within a localised indirection-id mapping table. The functionality detailed in this document allows a network controller to decouple the BGP flowspec redirection instruction from the operation of the available paths.
