Abstract: In some embodiments, a method inserts, by a first computing device, a first value for a capability in a first message that is used in a process to automatically exchange capability values with a second computing device. The first value for the capability indicates the first computing device requires a default route to reach the second computing device as a next hop for sending a packet to a destination. The first computing device sends the first message to the second computing device; and receives a second value for the capability in a second message from the second computing device. The second value indicating the second computing device will send the default route to reach the second computing device. When the default route is received from the second computing device, the first computing device stores the default route from the second computing device in a route table.

Abstract: The present disclosure provides an approach for scaling the number of VNFs in a data center without scaling the number of control sessions between VNFs and a data center gateway. The approach includes opening a session between a VNF and a route server, rather than between the VNF and the gateway, when the VNF needs to send its connectivity information to the gateway. The VNF sends its connectivity information to the route server, and the route server forwards the connectivity information to the gateway. The gateway receives connectivity information of a plurality of VNFs in the data center from the route server rather than from each of the VNFs individually. The connectivity information is then used to send packets, by the gateway to a VNF, for processing. The packets are sent using three layers of networking: an underlay physical network, an overlay logical network, and a second overlay logical network.
