The indirection-id table is the table construct of indirection-id On a flowspec client for policy-based forwarding onto an explicit The indirection-id is a 32-bit unsigned number, used as anchor point Making use of a 32-bit indirection-id using a new extended community.Įach indirection-id serves as anchor point, for policy-basedįorwarding onto an explicit path by a flowspec client.Ģ. This draft specifies a 'Redirect to indirection-id' flowspec action There is need to steer the traffic onto an explicitely defined Mitigation, however using this methodology can be cumbersome when To steer traffic towards an alternate destination is useful for DDoS Such as discard and rate limit it also defines a redirect-to-VRFĪction for policy-based forwarding. Theįlowspec standard rfc5575bis defines widely-used filter actions Policy instructions for traffic handling on the flowspec client. Part, encoded in one or more BGP extended communities, provides Information about the traffic matching the policy rule. The first part, encoded in the NLRI field, provides Particularly if the redirected traffic needs to be steered onto anĮvery flowspec policy route is effectively a rule, consisting of two Policy-based forwarding, but this mechanism is not always sufficient, Theįlowspec standard rfc5575bis defines a redirect-to-VRF action for This has many possibleĪpplications but the primary one for many network operators is theĭistribution of traffic filtering actions for DDoS mitigation.
