Zusammenfassung:Embodiments for handling multidestination traffic in a network are described. The multidestination traffic includes packets that are in transit to a multihomed destination in the network. Upon determining the destination is multihomed, a network switch determines a hash value from a selection of header values in the network traffic and uses the hash value to determine if the network switch is a designated forwarder for the multihomed destination. The network switch handles the network traffic according a designated forwarder status.
