A network device that processes packets and includes at least one legacy component for performing basic processing on packets in the network device. The network device further includes at least one advanced component for performing advanced processing, which can not be performed by the legacy component, on packets in the network device. When an incoming packet to the legacy component requires advanced processing, the legacy component performs the basic processing and transmits the packet to a loop-back port on advanced component. Upon receiving the packet, basic processing is disabled on the advanced component and advanced processing is performed on the packet.
