US Patent 11652881 Mirroring to multiple destinations using a monitoring function

In some embodiments, a method processes a first packet and generates a first copy of the first packet as a second packet. The method sends second copies of the first packet to a first group of multiple destinations defined by a first address. Also, the method sends the second packet to an interface with a loopback function. The interface recirculates the second packet for further processing. The second packet is processed where the second packet is assigned a destination of a second address. Then, the method sends copies of the second packet to a second group of multiple destinations defined by the second address.
