Abstract
In general, techniques are described for enhancing operations of virtual networks. In some examples, a network system includes a server that executes a virtual router configured to receive, from a switch fabric, a tunnel packet for a virtual network of the virtual networks, wherein the tunnel packet comprises an outer header and an inner packet that defines a packet flow. The virtual router is also configured to determine, based at least on the outer header, that the packet is associated with a virtual network of the one or more virtual networks, determine a packet flow defined by the inner packet does not match any flow table entry of a flow table that identifies active flows only for virtual network and, in response, add a flow table entry for a reverse packet flow of the packet flow to the flow table.
