Abstract: 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.

Abstract: In general, the disclosure describes examples where a single software-defined network (SDN) controller is configured to receive an indication of a first cluster identifier for a first cluster of computing devices and receive an indication of a second cluster identifier for a second cluster of computing devices. In response to a determination that first configuration information indicates the first cluster identifier, the SDN controller is configured to configure a first set of virtual routers at the first cluster to connect the first group of workloads to a network using the first configuration information. In response to a determination that second configuration information indicates the second cluster identifier, the SDN controller is configured to configure a second set of virtual routers at the second cluster to connect the second group of workloads to a network using the second configuration information.
