Abstract: Disclosed are systems, methods, and computer-readable storage media for gleaning MAC and IP address bindings. A networking switch facilitating data communication for a sub-network of a computer network can receive an ARP request from a VM included in the sub-network. The ARP request can include a MAC address and an IP address assigned to the VM. The ARP request can be transmitted by the VM as a result of the VM being added to the sub-network. The networking switch can transmit a reporting message to a control plane entity of the computer network. The reporting message can indicate that the VM has been added to the sub-network and include the MAC address and IP address assigned to the VM. The reporting message can cause the control plane entity to update a routing table for the computer network to include the MAC address and IP address assigned to the VM.

Abstract: Presented herein are hybrid approaches to multi-destination traffic forwarding in overlay networks that can be used to facilitate interoperability between head-end-replication-support network devices (i.e., those that only use head-end-replication) and multicast-support network devices (i.e., those that only use native multicast). By generally using existing tunnel end-points (TEPs) supported functionality for sending multi-destination traffic and enhancing the TEPs to receive multi-destination traffic with the encapsulation scheme they do not natively support, the presented methods and systems minimize the required enhancements to achieve interoperability and circumvents any hard limitations that the end-point hardware may have. The present methods and systems may be used with legacy hardware that are commissioned or deployed as well as new hardware that are configured with legacy protocols.
