Active Bridge Mode?

Hello Everyone,

I stumbled across RouterOS last night while searching for a way to create an “active bridge” using software on cheap hardware like Raspberry Pi or similar, so I am new to boards and product. I know lots about software and a little about networking, so forgive if there is a simple solution to the challenge - a push in the right direction is appreciated.

I need a bridge to connect two systems to network. The 2nd system needs to be able to impersonate the 1st system on demand, by using its IP and MAC. Can RouterOS be configured as such? Using API to update tables and then update back? I understand that having 2 systems on the network with the same IP and MAC is going to cause problems, so if I momentarily “flipped” traffic to the 2nd system and then “flipped” back it makes sense logically, but then again I don’t know if another solution is more elegant. I saw something about “pseduo-bridge” with “proxy ARP” that seemed to make sense but I wasn’t sure if that applied to ethernet or wireless only.

Network ------------------------ Router OS ------------------ System A
------------------ System B (same IP address and MAC as system A on demand)

Any suggestions? Is this Software-Defined Networking?

Thanks in advance…:slight_smile:
