Yes. At a first approximation, routing occurs whenever a
multiple-interface relay deencapsulates a frame, looks at the packet
header, sends the packet to another interface, and reencapsulates it
into a frame appropriate for this interface.
Tunneling gets more complex, but is a recursive application of the
same general principle.
