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.
