Abstract:
BGP Flow-spec is an extension to BGP that allows for the
dissemination of traffic flow specification rules. The primary
application of this extension is DDoS mitigation where the flowspec
rules are applied in most cases to all peering routers of the
network.
This document will present another use case of BGP Flow-spec where
flow specifications are used to maintain some access control lists at
network boundary. BGP Flowspec is a very efficient distributing
machinery that can help in saving OPEX while deploying/updating ACLs.
This new application requires flow specification rules to be applied
only on a specific subset of interfaces and in a specific direction.
The current specification of BGP Flow-spec does not detail where the
flow specification rules need to be applied.
This document presents a new interface-set flowspec action that will
be used in complement of other actions (marking, rate-limiting ...).
The purpose of this extension is to inform remote routers on where to
apply the flow specification.
This extension can also be used in a DDoS mitigation context where a
provider wants to apply the filtering only on specific peers.
