Techniques are described for learning an unknown virtual network information, such as an virtual Internet Protocol (IP) address, of a pod in a virtual network. In some examples, a virtual router executing at a computing device may receive an Address Resolution Protocol (ARP) packet from a virtual execution element in the virtual network, the virtual execution element executing at the computing device. The virtual router may determine, based at least in part on the ARP packet, whether virtual network information for the virtual execution element in a virtual network is known to the virtual router. The virtual router may, in response to determining that the virtual network information of the virtual execution element in the virtual network is not known to the virtual router, perform learning of the virtual network information for the virtual execution element.

In general, this disclosure describes techniques for a containerized router operating within a cloud native orchestration framework. In an example, a computing device comprises a containerized routing protocol process executing on processing circuitry of the computing device and configured to receive routing information; a containerized set of workloads; a data plane development kit (DPDK)-based virtual router executing on the processing circuitry and configured to forward traffic to and from the workloads based on the routing information from the containerized routing protocol; and a virtual router agent for the virtual router, the virtual router agent executing on the processing circuitry and configured to expose a generic data plane interface.

A network system includes a server comprising a set of virtual routers configured to extend virtual networks to virtual machines. A virtual router of the set of virtual routers may receive a tunnel packet comprising a outer header and an inner packet that defines a first packet flow, and determine, based at least on the outer header, that the tunnel packet is associated with a first virtual network of the virtual networks. The virtual router may also associate, based on the inner packet, the tunnel packet to a layer three link of a plurality of layer three links coupling the virtual router to two or more top-of-rack switches in the virtual network, where the plurality of layer three links form a layer three multi-homing connection between the virtual router and the top-of-rack switches in the virtual network. The virtual router may transmit the tunnel packet via the layer three link.
