A Thread Border Router connects a Thread network to other IP-based networks, such as Wi-Fi or Ethernet. A Thread network requires a Border Router to connect to other networks.
A Thread Border Router minimally supports the following functions:
- End-to-end IP connectivity via routing between Thread devices and other external IP networks
- External Thread Commissioning (for example, a mobile phone) to authenticate and join a Thread device to a Thread network
The quickest way to get started with OTBR is to try the Docker version. Run OTBR in a Docker container on any Linux-based system or a Raspberry Pi 3B, using either a physical or simulated RCP.
See the Docker Support Overview for more information.
OTBR also runs directly on a supported platform:
- Choose a platform:
- Build and configure OTBR
- Learn about tools and scripts included with OTBR

You can contribute to the ongoing development of OpenThread Border Router by submitting bug reports and feature requests to the Issue Tracker.
A member of the OT community has enabled OTBR support using QEMU, an open-source machine emulator and virtualizer. The project emulates Raspbian on an ARM architecture.
Features and services
OTBR includes a number of features, including:
- Web GUI for configuration and management
- Thread Border Agent to support external commissioning
- DHCPv6 Prefix Delegation to obtain IPv6 prefixes for a Thread network
- NAT64 for connecting to IPv4 networks
- DNS64 to allow Thread devices to initiate communications by name to an IPv4-only server
- Thread interface driver using OpenThread's built-in feature
- Docker support
Border Router services
OTBR provides the following services:
- mDNS Publisher — Allows an External Commissioner to discover an OTBR and its associated Thread network
- PSKc Generator — For generation of PSKc keys
- Web Service — Web UI for management of a Thread network
Third-party components for Border Router Services include Simple Web Server and Material Design Lite for the framework of the web UI.
