How to redirect if already logged in

[jaydeepesparkinfo]

Hi there ,
My configuration is
$authProvider.signinUrl = 'laravel-frontend/public/api/frontauthenticate';
$authProvider.signinState = 'login';
$authProvider.signinRoute = '/login';
$authProvider.signinTemplateUrl = 'app/shared/views/login.html';
$authProvider.afterSigninRedirectTo = 'dashboard';
$authProvider.afterSignoutRedirectTo = 'login';
so after login it goes to dashboard but then when I write '/login' then it opens login page.

How can I redirect it to dashboard if it is already looged in .

Thanks
