What is the primary function of bridging in MikroTik RouterOS?

• A. Bridging forwards frames at Layer 2, keeping devices in the same broadcast domain.
• B. Routing moves packets between IP subnets at Layer 3.
• C. Bridging automatically assigns IP addresses to interfaces.
• D. Routing uses MAC addresses to forward frames.

Answer: (A)

Briding in MikroTik RouterOS operates at Layer 2, focusing on Ethernet frames and MAC addresses. It combines multiple physical interfaces into one LAN segment, so all devices behind the bridge share the same broadcast domain. The bridge learns which MAC addresses are reachable on which ports and forwards frames only to the appropriate port (or floods if the destination MAC is unknown), keeping traffic contained within that single network. This is different from routing, which moves packets between IP subnets at Layer 3, and it also doesn’t automatically assign IP addresses to interfaces.
