Abstract
Methods and apparatus are disclosed for sending a multicast packet from multiple network interfaces across multiple networks using the same media access source address (MAC source address). One implementation includes a processing element and a network interface for each of the multiple networks. The processing element generates and initiates sending of a multicast packet having a same media access source address (MAC source address) from at least two of the multiple network interfaces. In one implementation, a single copy of the multicast packet is buffered, and each of the network interfaces retrieves, such as via a direct memory access (DMA) request, the multicast packet and forwards it to an attached network.
