In an embodiment, a network adapter receives a request from a first virtual switch of an overlay network to transmit a multi-destination packet to each of one or more virtual switches of the overlay network identified in a list stored in the network adapter. For each of the one or more virtual switches identified in the list, the network adapter creates a head-end replication of the multi-destination packet, obtains tunneling endpoint information for the identified virtual switch, encapsulates the created head-end replication of the multi-destination packet with a header specific to a tunneling protocol identified in the obtained tunneling endpoint information, and transmits the encapsulated packet to a receiver hosted on the identified virtual switch.
