Abstract
Aspects provide optimized broadcast, unknown unicast, multicast packet (BUM) flooding. A flooding interface list is built for a network virtualization edge structure for an overlay network first virtual machine that includes one or more tunnel interfaces, one for each of a subset of the underlay network virtualization edge structures. In response to receiving a BUM packet from the first virtual machine at the first network virtualization edge structure, an overlay encapsulated packet is generated from the BUM packet and sent out to only those tunnel interfaces listed within the flooding interface list built for the virtual machine, thereby without sending to other network virtualization edge structures that do not have tunnel interfaces listed within the built flooding interface list.
