It's a command prompt, not a "DOS prompt". CMD.EXE doesn't have anything

I'm well aware of the syntax of the "route" command shipped with
Windows as well as what it actually does, thank you very much.

Your example command defines that packets with a destination address
in the network range should be passed via interface 2 to a
next hop (or "gateway") with the address However, if the
host where you defined that route cannot (directly) reach the gateway
(or the gateway cannot forward the packets for some reason), the remote
network will be unreachable. IOW if they aren't already connected,
setting a route won't change anything about that.

There is no simple answer to that question. Too many factors could
influence the outcome (physical connectivity, routing tables on
intermediate routers, packet filters, etc.).
