What is the maximum number of bridges that can be added to a MikroTik router?

• A. One
• B. Unlimited
• C. Two
• D. Three

Answer: (B)

Bridges in MikroTik RouterOS are just separate Layer 2 domains you create by grouping interfaces. There isn’t a fixed cap on how many bridge objects you can make—the limit is effectively unlimited, driven only by the device’s memory and processing power. In other words, you can add as many bridges as your hardware can handle.

Each bridge has its own set of ports, and an interface can belong to only one bridge at a time, so you organize networks by assigning ports to the appropriate bridges. In practice, you’d create multiple bridges when you need multiple isolated L2 networks, but remember that more bridges mean more management overhead and potential CPU load if there are many traffic-heavy ports.
