Requests to IDR chairs:
  Can we start a WGLC on draft draft-ietf-idr-flowspec-path-redirect-07?

Key status updates on this draft:

1) Nokia has a commercial implementation of this draft released in latest router software (SROS16.0R4).

2) modified the following text in the draft (Chapter 6) to make the indication 'invalid flowspec action' decoupled from BGP as that makes more sense from operational perspective and reduces the complexity within BGP code:

     BEFORE:
     In addition the flowspec client MUST provide an indication within the BGP routing table that the
     respective "'Redirect to indirection-id" resulted in an invalid redirection action.

     AFTER:
     In addition the flowspec client MUST provide an indication that the respective "'Redirect to indirection-id" resulted
     in an invalid redirection action.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Inter-Domain Routing WG of the IETF.

        Title           : Flowspec Indirection-id Redirect
        Authors         : Gunter Van de Velde

Abstract:
   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.
