<p>When running on the same host, we need to pick different ports for the client connections <code>-p</code>, and for the port used to accept other routes <code>-cluster</code>. Note that <code>-routes</code> points to the <code>-cluster</code> address of the seed server (<code>localhost:4248</code>).</p>
<p>Here is the log produced. See how it connects and registers a route to the seed server (<code>...GzM</code>).</p>
