. Start server `jdg2`. There is a different multicast address, so the `jdg1` and `jdg2` servers are not directly clustered with each other; rather, they are just connected through the RELAY2 protocol, and the TCP JGroups stack is used for communication between them. The start up command looks like this:

. To verify that channel works at this point, you may need to use JConsole and connect either to the running `JDG1` or the `JDG2` server. When you use the MBean `jgroups:type=protocol,cluster="cluster",protocol=RELAY2` and operation `printRoutes`, you should see output like this:
