Routers in the network receive frames<br />
from layer 2, extract the layer 3 content<br />
(packet) and decide based on the global<br />
address to which outgoing connection<br />
(port) the packet has to be passed on.<br />
Accordingly the packet becomes payload<br />
of a new frame and is sent.<br />
