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 (traffic engineered)
tunnel egress interface.
