Test the Default Multicast Address

The run script uses a multicast address, either the default address or an alternative address supplied by your network administrator.

To test the default multicast address

1. Run sender on first node as follows:
   1. Navigate to jboss-home-1/server/all/lib.
   2. Run: java -cp jgroups.jar org.jgroups.tests.McastSenderTest -mcast_addr 224.10.10.10 -port 5555
2. Run receivers on other nodes in the cluster as follows:
   1. Navigate to jboss-home-N/server/all/lib.

      N represents the next node in the cluster.

   2. Run: java -cp jgroups.jar org.jgroups.tests.McastReceiverTest -mcast_addr 224.10.10.10 -port 5555
3. Send a message from the first node as follows:
   1. On the console of the first node, enter any text and press enter.
   2. Confirm that a reply appears, to acknowledge the text was sent.
   3. Confirm that the message appears on the console of all other nodes in the cluster.
   4. If either the send or receive test fails, ask your network administrator to provide a multicast address that works and repeat this test.
