Abstract
A network device may create an encrypted packet and may duplicate the encrypted packet to create a plurality of encrypted packets that includes a first set of encrypted packets that is associated with a first receiving network device and a second set of encrypted packets that is to be associated with a second receiving network device. The network device may modify the second set of encrypted packets by replacing a first virtual destination address in the second set of the plurality of encrypted packets with a second virtual destination address that identifies a virtual tunnel endpoint of the second receiving network device. The network device may encapsulate and may send, based on the first virtual destination address and the second virtual destination address, individual encapsulated encrypted packets to the first receiving network device or the second receiving network device.
