Abstract:
   Flow-spec is an extension to BGP that allows for the dissemination of
   traffic flow specification rules.  This has many possible
   applications but the primary one for many network operators is the
   distribution of traffic filtering actions for DDoS mitigation.  The
   flow-spec standard RFC5575 [2] defines a redirect-to-VRF action for
   policy-based forwarding but this mechanism is not always sufficient,
   particular if the redirected traffic needs to be steered into an
   engineered path or into a service plane.

   This document defines a new redirect-to-INDIRECTION_ID (32-bit or
   128-bit) flow-spec action to provide advanced redirection
   capabilities.  When activated, the flowspec Indirection-id is used to
   identify the next-hop redirect information within a router locallized
   Indirection-id table.  This allows a flowspec controller to signal
   redirection towards a next-hop IP address, a shortest path tunnel, a
   traffic engineered tunnel or a next-next-hop engineered tunnel
   interface.
