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 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.

This question came from our site for professional and enthusiast programmers.

Routing table entries tell your local computer which one of its interfaces to use when trying to send data to a given address. You cannot use it to tell the machine to send packets intended for one address to another address.
