Abstract
Example methods are provided for first host to perform multicast packet handling in a software-defined networking (SDN) environment. The method may comprise: in response to the first host detecting, from a first virtualized computing instance, a request to join a multicast group address, obtaining control information from a network management entity. The control information may include one or more destination addresses associated with one or more second hosts that have joined the multicast group address on behalf of multiple second virtualized computing instances. The method may also comprise: in response to the first host detecting an egress multicast packet that includes an inner header addressed to the multicast group address, generating one or more encapsulated multicast packets based on the control information and sending the one or more encapsulated multicast packets in a unicast manner or multicast manner, or a combination of both.
