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 VPNs.
This draft proposes a new redirect-to-IP flow-spec action that
provides a simpler method of policy-based forwarding. This action is
indicated by the presence of a new BGP extended community in the
flow-spec route. Many routers already support a redirect-to-IP filter
action and, in this case, the only new functionality implied by this
draft is the ability to signal the action using flow-spec.
