Which option correctly shows how to create a bridge named bridge1 and attach two interfaces?

• A. /interface bridge add name=bridge1
• B. /interface bridge port add bridge=bridge1 interface=ether1; /interface bridge port add bridge=bridge1 interface=ether2
• C. /interface bridge port add bridge=bridge1 interface=ether1
• D. /interface bridge add name=bridge2

Answer: (B)

In RouterOS, a bridge acts as a virtual switch and you attach interfaces to it with bridge port commands. To attach multiple interfaces in one go, you use the bridge port add command for each interface, and you can separate those commands with a semicolon on the same line. Attaching both ether1 and ether2 to the bridge named bridge1 is exactly what this approach does: it runs two port additions, one for ether1 and one for ether2, both referencing bridge1. This is the correct way to connect multiple interfaces to a single bridge in one step. The other options either create the bridge without attaching interfaces, attach only one interface, or specify a different bridge name, so they don’t fulfill the requirement of attaching two interfaces to bridge1.
