Thank you Justin for your reply and invitation on Slack. Because you mentioned a larger audience on this mailing list, let me describe my issue here.
I am configuring AMQ to form a simple fanout federation like (top broker) --> (middle broker) --> (bottom broker), where an arrow represents upstream to downstream relationship. According to the AMQ document, I only configured a downstream broker to connect to an upstream broker using a simple static connector and forward-all "#" address for federation. However, when I connect an MQTT publisher to the top broker and an MQTT subscriber to the bottom one, the latter cannot receive the sent message. When I instead connect the subscriber to the middle broker, it can receive the message, and the same applies when I connect publisher to middle and subscriber to bottom. In other words, the federation only works when brokers are "one hop" away and does not work when they are further apart. AMQ documents do not provide details on how to configure fanout topology except to set max-hops, and all the activemq federation examples are basically "one-hop-away" type. Therefore, may I ask the community how I can make fanout federation works, and even better may I have an example broker.xml for a fanout? Below are basic setups on my side. OS: Ubuntu 22.04 AMQ: v2.36.0 Thank you, Patrick On Mon, Sep 16, 2024 at 11:45 AM Justin Bertram <jbert...@apache.org> wrote: > This mailing list is the right place to ask questions about all things > ActiveMQ. > > The Slack channel is currently active.
