Abstract: Some embodiments provide a method for forwarding a data message. The method performs a lookup to map a set of header fields of the data message to an identifier corresponding to a service that performs non-forwarding processing on data messages. The method uses a dynamically-updated data structure for the identifier to retrieve instructions for forwarding data messages to the service. The method forwards the data message according to the retrieved instructions from the data structure for the identifier.

Abstract: In an embodiment, a method for a VRF and multi-service insertion on edge gateways is described. In an embodiment, the method comprises: detecting a packet; determining attributes for the packet; based on the attributes, determining whether the attributes match one or more rule attributes of a particular rule in a rule table; in response to determining that the attributes match the one or more rule attributes of a particular rule in the rule table: determining, based on the particular rule, a particular redirection identifier, a particular VRF identifier, a particular next_hop, a particular address pair, and a particular BFD status; based on the particular BFD status, determining whether to redirect the packet; and in response to determining to redirect the packet, redirecting the packet toward a service virtual machine from an interface indicated by one of addresses in the particular address pair.

Abstract: In an embodiment, a method for a VRF and multi-service insertion on edge gateways is described. In an embodiment, the method comprises obtaining a rule configuration. Based on, at least in part, the rule configuration, a rule table is created. The rule table comprises rule data records, wherein a rule data record comprises packet attributes and a redirection identifier. A policy configuration comprising policy records is obtained. Each policy record comprises a redirection identifier, a next_hop, and an address pair for interfaces. A mapping between VRF identifiers and address pairs is generated. Based on, at least in part, the mapping and the policy configuration, a policy table is generated. The policy table comprises table records, wherein a table record comprises a redirection identifier, a next_hop, and an address pair. The rule and policy tables are used to redirect a packet from an edge gateway to a service virtual machine.
