Mosquitto Bridge topic setting ignoring pattern

I have a setup with two MQTT Brokers (Mosquitto), remote and local. Remote handles a lot of traffic, local is supposed to act as a bridge and only forward a small subset of remote's topics. So far, this is my mosquitto.conf for broker local:

connection bridge
address remote.com
notifications false
topic test/1 in 0

From what I understood, that configuration would make the local broker connect to remote and only subscribe to test/1. Still, when subscribing to '#' of local broker, all of remotes messages arrive through local, not only test/1.

Is there any way to make my bridge forward only one certain topic or topic tree from the broker remote?

Solution

  • As @Brits kindly explained in his comment, all the topics were coming through since on my first bridge attempt, I used '#' as the pattern. That pattern seems to have persistet in all subsequent connections, until I used cleansession true once.

    Thanks for the help.
