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.

Abstract: An example method of packet processing in a host cluster of a virtualized computing system includes: receiving traffic at packet processing software of a hypervisor executing on a host of the host cluster; processing the traffic using a network service of the packet processing software in the hypervisor; redirecting the traffic to a service virtual machine (VM) in the host cluster through a virtual network interface card (vNIC) of the service VM; sending metadata from the network service of the packet processing software to the service VM; processing the traffic and the metadata through at least one network service executing in the service VM; returning the traffic from the service VM to the packet processing software of the hypervisor; and forwarding, by the packet processing software, the traffic to a destination.
