    Abstract: A system for efficient multicast forwarding at a switch is provided. During operation, the switch can maintain a first tunnel with a first switch in a first overlay tunnel fabric, and a second tunnel with a second switch in a second overlay tunnel fabric. The switch can operate as the gateway for both fabrics. The system can obtain a first fabric identifier and a second fabric identifier from multicast control packets received via the first and second tunnels, respectively. A fabric identifier can uniquely identify a fabric. The system can then store, in a data structure, a first network address of the first switch and a second network address of the second switch in association with the first and second fabric identifiers, respectively. The system can determine whether to forward multicast traffic to either one of the first and second fabrics based on the first and second fabric identifiers, respectively.

    Abstract: According to one or more embodiments of the disclosure, an edge node of a virtual overlay for a Layer-2 mesh receives a new flow notification that indicates a destination address for a new flow in the Layer-2 mesh. The virtual overlay is configured to flood replicated frames of the new flow throughout the virtual overlay. The edge node makes a local match between the destination address indicated by the new flow notification and a local address table of the edge node. The edge node sends, based on the local match, a match notification that causes other nodes in the virtual overlay to stop flooding replicated frames of the new flow.
