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 [RFC 5575] defines a redirect-to-VRF action for
policy-based forwarding but this mechanism can be difficult to use,
particularly in networks without L3 VPN infrastructure.
This draft defines a new redirect-to-IP flow-spec action that
provides a simpler method of policy-based forwarding. The details of
the action, including the IPv4 or IPv6 target address, are encoded
in newly defined BGP extended communities.
