title: Angular 2 routing redirect to with child routes
body: <p>I am a newbie in Angular 2. I want to create isolated modules for every part of my app. For example I created the <code>AuthModule</code> with default component - <code>AuthComponent</code> which contain a <code>router-outlet</code> for his child components (SignIn or SignUp). So I want to realise the following scenario:</p>
  
  <ol>
  <li>When navigate to / - root off app - redirect to /auth</li>
  <li>After redirect to /auth - load AuthComponent with router outlet</li>
  <li>After AppComponent loaded - load default sign-in component via redirecting to /auth/sign-in</li>
  </ol>
  
  <p>But when I going to localhost/ I get redirect to /auth what I want, but the next redirect to sign-in doesn't appear. </p>
  
  <p>My code:
  <code>app.routing</code></p>
  
  <pre><code>const routes: Routes = [
    {
        path: '', 
        redirectTo: '/auth', 
        pathMatch: 'full'
    }
  ];
  
  export const appRouting: ModuleWithProviders = RouterModule.forRoot(routes);
  </code></pre>
  
  <p><code>auth.routing</code></p>
  
  <pre><code>const routes: Routes = [
    {
      path: 'auth',
      component: AuthComponent,
      children: [
        {
           path: '', 
           redirectTo: 'sign-in', 
           pathMatch: 'full'
        },
        {
           path: 'sign-in', 
           component: SignInComponent
        }
      ]
    },
  
  ];
  
  export const authRouting: ModuleWithProviders = RouterModule.forChild(routes);
  </code></pre>
  
  <p><code>auth.component.html</code></p>
  
  <pre><code>&lt;div class="container"&gt;
      &lt;h1&gt;Auth component&lt;/h1&gt;
      &lt;router-outlet&gt;&lt;/router-outlet&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Result:</p>
