Yes. This scenario is possible through loop back interface. Since classifier is enabled on the interface level the packets coming back through the loopback interface will be classified into their respective flow in your example it will be flow #2 Hopefully the processing on the initial packet changes the packet header fields or the fields which are configured as part of PMR rule. Another example could be that the incoming packet is encrypted and the initial processing decrypts the packets and sends it to the loopback interface to be classified into a different flow.

[lng-odp] [HELP] Question about API Classification and Traffic Manager
Hi! I have some questions about Traffic Manager and Classifier. Traffic Manager: I see there is the possibility to send back the packets. Do you have any example where this would be used ? I don't really see how we can combine the different algorithms, example Strict Priority scheduling with Bandwidth Shaping, etc. http://img11.hostingpics.net/pics/882875tarfficmanager.png Classifiers It is possible to have such a loopback ? http://img11.hostingpics.net/pics/729760loop.png For example, a packet is classified in flow #1 with processing #1, and then is classified in flow #2 with processing #2, etc. ?
