Abstract:
   Dissemination of the Traffic flow information was first introduced in
   the BGP protocol [RFC5575].  FlowSpec routes are used to distribute
   traffic filtering rules that are used to filter Denial-of-Service
   (DoS) attacks.  For the networks that only deploy an IGP (Interior
   Gateway Protocol) (e.g., OSPF), it is required that the IGP is
   extended to distribute Flow Specification or FlowSpec routes.

   This document discusses the use cases for distributing flow
   specification (FlowSpec) routes using OSPF.  Furthermore, this
   document defines a OSPF FlowSpec Opaque Link State Advertisement
   (LSA) encoding format that can be used to distribute FlowSpec routes,
   its validation procedures for imposing the filtering information on
   the routers, and a capability to indicate the support of FlowSpec
   functionality.
