New Angular2 router configuration

Solution 1:

In the new router (>= RC.3) https://angular.io/docs/ts/latest/api/router/index/Router-class.html resetConfig can be used

router.resetConfig([
 { path: 'team/:id', component: TeamCmp, children: [
   { path: 'simple', component: SimpleCmp },
   { path: 'user/:name', component: UserCmp }
 ] }
]);

You might need to provide some dummy router configuration to not get errors on application startup.
