    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: Some embodiments provide novel methods for performing services for machines operating in one or more datacenters. For instance, for a group of related guest machines (e.g., a group of tenant machines), some embodiments define two different forwarding planes: (1) a guest forwarding plane and (2) a service forwarding plane. The guest forwarding plane connects to the machines in the group and performs L2 and/or L3 forwarding for these machines. The service forwarding plane (1) connects to the service nodes that perform services on data messages sent to and from these machines, and (2) forwards these data messages to the service nodes. In some embodiments, the guest machines do not connect directly with the service forwarding plane. For instance, in some embodiments, each forwarding plane connects to a machine or service node through a port that receives data messages from, or supplies data messages to, the machine or service node. In such embodiments, the service forwarding plane does not have a port that directly receives data messages from, or supplies data messages to, any guest machine. Instead, in some such embodiments, data associated with a guest machine is routed to a port proxy module executing on the same host computer, and this other module has a service plane port. This port proxy module in some embodiments indirectly can connect more than one guest machine on the same host to the service plane (i.e., can serve as the port proxy module for more than one guest machine on the same host).

    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.
