You can optionally assign a Broker to function as the default Broker for a Broker Server. The default Broker is the one to which a Broker Server will route client requests that are not addressed to a specific Broker.

When you install Broker Server using Software AG Installer, it installs one Broker, which it designates it as the default. You can change this designation if you install additional Brokers on the Broker Server.

A Broker Server is not required to have a default Broker. However, if your Broker clients are designed to connect to the default Broker (that is, they do not explicitly specify a Broker name when they connect to Broker Server), you must designate a default. Otherwise, requests from those clients will be rejected.
