redirect to a page programmatically in react-router 2

I am using react-router-2. I want to redirect to a page programmatically after successful login or after some action performed.

My route file is like this(routes.js)

   <Route path="/" component={App}>
       <IndexRoute component={Home}/>
       <Route path="/login" component={Login} onEnter={redirectToDashboard}/>
       <Route path="dashboard" component={Dashboard} onEnter={redirectToLogin}/>
   </Route>

onEnter hooks

function redirectToLogin(nextState, replace) {
    // Perform some authentication check
    if (!loggedIn) {
        replace({
            pathname: '/login',
            state: { nextPathname: nextState.location.pathname }
        });
    }
}

function redirectToDashboard(nextState, replace) {
  // Perform some check if already authenticated 
    if (loggedIn) {
        replace('/dashboard')
    }
}

I want to redirect to Dashboard component from Login component after successful login.
