This is a follow up question to this: Angular 2 how does auxiliary routes work in 2.1.0?
I also tried looking at this but it doesn\'t really shed any light on the issue:
Try with:
const routes: Routes = [ { path: '', component: DashboardComponent, children: [ { path: 'brands', loadChildren: '../pages/+brands/brands.module#BrandsModule' } ] } ];
and /admin/(admin:dashboard//brands)
/admin/(admin:dashboard//brands)
