Hello Po
Let me explain with an example. If we have this topology:
…and there is traffic going between all of the hosts on the left and the server on the right, then all traffic in both directions will have:
- source and destination MAC addresses of the hosts and of the server.
- source and destination IP addresses of the hosts and of the server.
In this case, src-ip for Network A to B (IP addresses of the 60 hosts) and src-mac for Network A to B (MAC addresses of the 60 hosts) will have the same result. The IP addresses correspond exactly to the MAC addresses.
In the other direction, dest-ip on Network B to A (IP addresses of the 60 hosts) and dest-mac on network B to A (MAC addresses of the 60 hosts) will also work the same way for the same reason.
I hope this has been helpful!
