It is widely known that a network packet can be sent forcely to a designated port(a physical port in switch hub device) by adding a route table entry. For example,
(In Windows Console in host A) c:>route add B mask 255.255.255.255 X Enforces any packet from A to B to go to the host X.
However, I recently found that it cannot be done unless host A allows adding a route table entry.
I don't know about L3 switch devices, however, I just guess it may be resolved by adding an route table entry in L3 switch device configuration, but I am not sure.
Is there any way to add that route table entry not in host A, but in other way?
Please reply. Thanks in advance.
