Incoming messages from a client connected to broker2 on the topic b2/ house/sensor1. Incoming messages from a client connected to broker1 on topic b1/house/sensor1 are being bridged and will be remapped and sent to broker2 on the topic b2/ house/sensor1. will be sent to broker1 on topic b2/ house/sensor1.Д«roker1 removes the b2 prefix and will send them to clients subscribed to house/sensor1 on broker 1. Incoming messages from a client connected to broker2 on topic b2/ house/sensor1. Incoming messages from a client connected to broker 1 on the topic house/sensor1 are being bridged and will be remapped and sent to broker2 on topic b2/ house/sensor1.

Normal clients will also be connected to both brokers. The following examples refer to the schematic above with two brokers Broker1 and B roker2. A message published to broker 2 on house/sensor1 is not sent to broker 2 as it doesnвЂ™t have the b2/ prefixД«roker2 is functioning as a normal broker (not a bridge) and doesnвЂ™t normally need any extra configuration.

When a client publishes a message to broker2 then messages published on b2/# are sent from broker2 to broker 1 but without the b2/ prefix.

Example incoming client message to B1 on topic house/sensor1 is published to broker 2 on topic b2/house/sensor1.

When Client1 publishes on any topic that message will be sent to broker 2 with the topic prefix b2/.

The screen shot below shows a remapping configuration for broker 1: When the bridge on broker1 subscribes to a topic on broker1 it uses the form: When the bridge on broker1 subscribes to a topic on broker2 it uses the form This is accomplished using the local and remote prefixes.

The screen shot below shows how to bridge all topics with no remapping. Example 2Д¬lient1 publishes to any topic and nothing is sent to broker B2.Д¬lient 2 publishes on house/sensor1 or house/anything and the message is sent to broker B1Д¬lient 2 publishes on house1/sensor1 and the message is not sent to broker B1 Example 3Д¬lient 1 publishes on house/sensor1 or house/anything and the message is sent to broker B2Д¬lient 1 publishes on house1/sensor1 and the message is not sent to broker B2Д¬lient 2 publishes on house1/sensor1 and the message is not sent to broker B1 This is best seen in examples using the layout in the schematic belowД¬lient 1 publishes on house/sensor1 or house/anything and the message is sent to broker 2Д¬lient 1 publishes on house1/sensor1 and the message is not sent to broker 2Д¬lient 2 publishes to any topic and nothing is sent to broker B1. Note: If you arenвЂ™t using topic prefixes then you donвЂ™t need to add them. Topic topic pattern direction QOS local prefix/ remote prefix. Wildcards can be used in the topic entry. What topics are being bridged, and if they are being remapped is controlled by the topic entry. Note: You can configure multiple remote broker addresses and the broker will switch to another broker if the current broker connection fails. What topics the broker will publish, and which topics it will subscribe to.

The Address and port of the remote broker or brokers.

When you configure the mosquitto broker to act as a bridge it becomes an MQTT client to the remote broker and subscribes and publishes to topics on the other broker just like a normal MQTT client.

In addition you only need to configure 1 of the brokers to act as the bridge, the other will act as a normal broker. Generally the local edge bridge will only bridge a subset of the local MQTT traffic. The Mosquitto broker (server) can be configured to work as an MQTT bridge. They are generally used for sharing messages between systems.ДЄ common usage is connect edge MQTT brokers to a central or remote MQTT network. A MQTT bridge lets you connect two MQTT brokers together.
