This should work.

tabs.router.module.ts

...
const routes: Routes = [
  {
    path: 'tabs',
    component: TabsPage,
    children: [
      {
        path: 'tab1',
        children: [
          { path: '', loadChildren: '../tab1/tab1.module#Tab1PageModule'}
        ]
      },
      ...
      { path: '', redirectTo: '/start/tabs/tab1', pathMatch: 'full'}
    ]
  }
];
...

app-routing.module.ts

...
const routes: Routes = [
  { path: '', redirectTo: 'login', pathMatch: 'full' },
  { path: 'start', loadChildren: './tabs/tabs.module#TabsPageModule' },
  { path: 'login', loadChildren: './login/login.module#LoginPageModule' },
];
