4.4. Pre-configured Exchanges

Out of the box, the Red Hat Enterprise Messaging broker has five pre-configured exchanges that you can use for messaging. These exchanges are all configured as durable, so they are available whenever the broker is started:
Default exchange
A nameless direct exchange. All queues are bound to this exchange by default, allowing them to be accessed by queue name.
amq.direct
The pre-configured named direct exchange.
amq.fanout
The pre-configured fanout exchange.
amq.match
The pre-configured headers exchange.
amq.topic
The pre-configured topic exchange.
