3 ActiveMQ servers clustered together in a mesh foramt:
broker1 / \ / \ / \ broker2 ------ broker3
This configuration is redundant - a failure in any one connection will result in the traffic being rerouted via other links.
Pay attention to the names in the config file as well as the users. This is identical to the simple single broker example except with the aded amq user for the clustering and the connection setups in broker1
This configuration requires at least version 5.4.0 of ActiveMQ
