<div class="wiki-content maincontent"><p>By default, the <a shape="rect" href="xml-configuration.xml">ActiveMQ xml configuration</a> includes the <a shape="rect" href="discovery.xml">multicast discovery</a> mechanism. The tcp transport connector advertises its self using multicast and a multicast network connector is configured to listen to the same address. In this way, all brokers that share the default multicast address will automatically network with each other. <br clear="none"> If multicast is not required, the multicast attributes of the Transport Connector and Network Connector can be removed.</p><p>To stop advertising your connection URI on the multicast network remove the discoveryUri attribute from the &lt;transportConnector/&gt;:</p><p>replace:</p><div class="code panel pdl" style="border-width: 1px;"><div class="codeContent panelContent pdl">
