Wired Network Configuration

#Routers

Wired network parameters are configured in the /network/bridge section.

wired1

A bridge is a virtual Layer 2 (L2) network device that integrates physical or logical interfaces into a single network segment.

The bridge operates as a virtual switch, aggregating multiple physical interfaces (configurable in /network/ethernet) or logical network interfaces (configurable in /network/device, /wireless/network, or /tunnel). By default, all device ports are grouped into bridge0.

Basic Parameters

  • Disabled — Disables the bridge.

  • MAC — Assigns a MAC address. If not specified, the address is generated automatically.

  • Port — Configures the list of interfaces aggregated within the bridge.

Configuration Example

Objective:

To integrate devices connected to port2 and port4 into a single network segment.

Procedure:

  1. Release the ports:

    • Navigate to /network/bridge/bridge0.

    • Remove port2 and port4 from the list by clicking the minus (-) button.

    • Apply the settings by clicking Apply.

wired2
Do not remove the port used to connect the router to the PC. This will result in loss of access to the device.

  1. Create a new bridge:

    • Navigate to the /network/bridge section.

    • Click Add to create a new bridge and specify a name (e.g., bridge1). Permitted characters include letters (A-Z, a-z), digits (0-9), and underscores (_).

    • Add the required interfaces from the Port dropdown menu (in this example: port2, port4).

    • Apply the settings by clicking Apply.

wired3 2

Both virtual network devices and their respective parameters are now displayed on the /network/bridge page.

wired4

  1. Assign an IP address:

    • Navigate to /ip/interface.

    • Click Add and select bridge1 from the list (created in step 2).

    • Specify the type as static.

      wired5

    • Go to the newly created interface at /ip/interface/bridge1.

    • Enter the IP address (e.g., 192.168.2.1/24).

    • Apply the settings by clicking Apply.

Both virtual network devices and their respective parameters are now displayed on the /ip/interface page.
