A network device includes a first circuit configured to generate a plurality of packets, and insert, in each of the plurality of packets, a different value for a count. A second circuit receives one or more of the plurality of packets. A third circuit generates a plurality of seeds. Each of the plurality of seeds is based on (i) a predetermined key, (ii) an address of the network device, and (iii) a predetermined value for the count. A fourth circuit encapsulates each of the plurality of packets using one of the plurality of seeds generated based on the value for the count in the respective one of the plurality of packets. A fifth circuit sends a message comprising (i) the address of the network device and (ii) the predetermined value for the count, and sends, subsequent to sending the message, the plurality of encapsulated packets.
