title: How to change useless repeat Route
body: <p>I am working with react-router for the first time.</p>
  
  <p>Here is my piece of code.</p>
  
  <pre><code> &lt;Switch&gt;
      &lt;Route exact path="/" component={Home} /&gt;
      &lt;Route path="/A/xx/xxx/:feeros" component={About} /&gt;
      &lt;Route path="/B/xx/xxx/:feeros" component={About} /&gt;
      &lt;Route path="/C/xx/xxx/:feeros" component={About} /&gt;
      &lt;Route path="/D/xx/xxx/:feeros" component={About} /&gt; 
    &lt;/Switch&gt;
  </code></pre>
  
  <p>This part of the <code>&lt;Route path="//xx/xxx/:feeros" component={About} /&gt;</code> code is always repeated.There is no way to reduce this react router ?</p>
