title: Angular 2: Have Child Route Component Replace Parent in router-outlet
body: <p>Is there a way to display a child route in the parent route's <code>&lt;router-outlet&gt;</code>?</p>
  
  <p>For example, let's say we have two routes:</p>
  
  <pre><code>/users/12345
  
  /users/12345/orders/12345
  </code></pre>
  
  <p>I need the second to be a child of the first, but I also need to completely replace the contents of <code>/users/12345</code> with the contents of <code>/users/12345/orders/12345</code> opposed to having <code>/users/12345/orders/12345</code> in the <code>/users/12345</code> sub <code>router-outlet</code>.</p>
  
  <p>I thought I could do this by just naming the parent level router-outlet and have both routes target it, but from the research I've been doing (and the errors it caused) I get the feeling the names were intended for secondary uses when there already exists a primary router-outlet</p>
