MikroTik: Bridge Interface with Multiple Ports

Introduction

Setting up a bridge interface on a MikroTik device allows you to unify multiple physical interfaces into a single logical network. This is especially useful for connecting wired and wireless networks or managing traffic across various Ethernet ports. In this guide, you’ll learn how to configure a bridge interface on your MikroTik device and add multiple interfaces, including Ethernet and wireless.

More information about bridge intraface on MikroTik devices you can finde on the link.

Why Use a Bridge Interface?

A bridge interface connects multiple ports into a single broadcast domain, allowing seamless communication among devices. Use cases include:

Combining wired and wireless networks.
Extending the network across multiple physical interfaces.
Simplifying network management

Step-by-Step Bridge Configuration with WinBox

Step 1: Log in to MikroTik Router

Access your router via the MikroTik WinBox application or the web interface. Use your credentials to log in.

Step 2: Navigate to the `Bridge`

Go to the Bridge menu in Winbox.Click Add (+) to create a new bridge.Name the bridge, e.g., intern

Step 3: Add Interfaces to the Bridge

Go to the Ports tab under the Bridge menu.
Click Add (+) to add interfaces.
Select interfaces such as eth2, eth3, eth4, eth5, and wlan.
Assign each to the bridge you created (e.g., LAN-Bridge).

Step 4: Verify Configuration

Go to the Bridge menu and check the status.
Ensure that all selected interfaces are listed under the bridge.
Test connectivity between devices connected to the ports.

Check if the interfaces are add in the Bridge

Configuration via CLI

Using the MikroTik Command Line Interface (CLI) is an efficient way to configure a static IP address. Here’s a step-by-step guide:

Step 1: Copy following script in the terminal

/interface bridge
add fast-forward=no name=intern

/interface bridge port
add bridge=intern interface=ether2
add bridge=intern interface=wlan1
add bridge=intern interface=ether3
add bridge=intern interface=ether4
add bridge=intern interface=ether5
