On some implementation you may wish to use multiple tasks, like this.::

drop=no
- In this example you can see Core 1/Task 0 called ``rx_task`` receives the packet from if0 and perform the l2fwd. However instead of sending the packet to a
- port it sends it to a core see ``tx cores=1t1``. In this case it sends it to Core 1/Task 1.
