I am new to Artemis. I have two artemis server up and running but when I send broadcast messages then the messages are sent to only one server.
Following is the snippet of broker.xml of brokerOne

And here is how I am creating producer/consumer and sending messages. I took this example from artemis documentation and modified it to fit my case.
public class Main {
public static void main(String[] args) {
try {
new Main().runExample();
} catch (Exception e) {
e.printStackTrace();
}
}
public void runExample() throws Exception {
InitialContext initialContext = null;
Connection connectionA = null;
Connection connectionB = null;
try {
Properties properties = new Properties();
properties.put("java.naming.factory.initial", "org.apache.activemq.artemis.jndi.ActiveMQInitialContextFactory");
properties.put("connectionFactory.ConnectionFactory", "udp://231.7.7.7:9876");
properties.put("queue.queue/ExpiryQueue", "ExpiryQueue");
initialContext = new InitialContext(properties);
Queue queue = (Queue) initialContext.lookup("queue/ExpiryQueue");
ConnectionFactory connectionFactory = (ConnectionFactory) initialContext.lookup("ConnectionFactory");
Thread.sleep(5000);
//brokers of both servers has same username and password
connectionA = connectionFactory.createConnection("admin", "admin");
connectionB = connectionFactory.createConnection("admin", "admin");
Session sessionA = connectionA.createSession(false, Session.AUTO_ACKNOWLEDGE);
Session sessionB = connectionB.createSession(false, Session.AUTO_ACKNOWLEDGE);
System.out.println("Session A - " + ((ClientSessionInternal)
((org.apache.activemq.artemis.jms.client.ActiveMQSession) sessionA)
.getCoreSession()).getConnection().getRemoteAddress());
System.out.println("Session B - " + ((ClientSessionInternal)
((org.apache.activemq.artemis.jms.client.ActiveMQSession) sessionB)
.getCoreSession()).getConnection().getRemoteAddress());
MessageProducer producerA = sessionA.createProducer(queue);
MessageProducer producerB = sessionB.createProducer(queue);
final int numMessages = 10;
for (int i = 0; i < numMessages; i++) {
TextMessage messageA = sessionA.createTextMessage("A:This is text message " + i);
producerA.send(messageA);
System.out.println("Sent message: " + messageA.getText());
TextMessage messageB = sessionB.createTextMessage("B:This is text message " + i);
producerB.send(messageB);
System.out.println("Sent message: " + messageB.getText());
}
connectionA.start();
connectionB.start();
consume(sessionA, queue, numMessages, "A");
consume(sessionB, queue, numMessages, "B");
} finally {
// Step 10. Be sure to close our resources!
if (connectionA != null) {
connectionA.close();
}
if (connectionB != null) {
connectionB.close();
}
if (initialContext != null) {
initialContext.close();
}
}
}
private static void consume(Session session, Queue queue, int numMessages, String node) throws JMSException {
MessageConsumer consumer = session.createConsumer(queue);
for (int i = 0; i < numMessages; i++) {
TextMessage message = (TextMessage) consumer.receive(2000);
System.out.println("Got message: " + message.getText() + " from node " + node);
}
System.out.println("receive other message from node " + node + ": " + consumer.receive(2000));
}
}
I am executing the main class on the system with IP (10.5.100.1) and it is sending messages to only the IP (10.5.100.2). Why my program is behaving this way?
