US Patent 10103902 Auto-discovery of replication node and remote VTEPs in VXLANs

This disclosure describes techniques for utilizing VXLANs within a network, such as a data center, for transporting L2 customer communications. Moreover, the disclosure describes techniques for auto-discovering, for each VXLAN, a corresponding replication node for replicating and distributing unknown destination, broadcast, and multicast frames to VXLAN Tunnel Endpoints (“VTEPs”) within the data center. Further, the techniques facilitate, by the replication node, discovery and auto-registration of the VTEPs for the respective customer network. As such, the techniques may facilitate configuration of VXLANs without necessarily relying on multicast protocols to provide such functionality. In this way, the techniques described herein may be used to supplement or even replace reliance on multicast protocols, such as the Protocol Independent Multicast (PIM) protocol, when configuring VXLANs within a network.
