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 the Denial-of-Service
   (DoS) attacks.  For the networks that only deploy IGP (Interior
   Gateway Protocol) (e.g.  OSPF), it is expected to extend the IGP 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 new 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.
