               Flowspec Indirection-id Redirect for SRv6
             draft-ietf0-idr-srv6-flowspec-path-redirect-00

Abstract

   This document defines extensions to "FlowSpec Redirect to
   indirection-id Extended Community" for SRv6.  This extended community
   can trigger advanced redirection capabilities to flowspec clients for
   SRv6.  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.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [2].

1.  Introduction

   "FlowSpec Redirect to indirection-id Extended Community" for IPv4 is
   defined in ietf-idr-flowspec-path-redirect [1].  This draft specifies
   extensions to this community for SRv6.

2.  Redirect to indirection-id Community

   This document defines a new sub-type value for SRv6 in "FlowSpec
   Redirect to indirection-id Extended Community".  The format of this
   extended community with the new sub-type value is show below:

    0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
