Advance Laravel 5 Routing with optional paramaters

The following is the route

Route::get('{value1}/{optvalue1?}/{optvalue2?}/{value2}/{value3}/',
        [
            'uses'  => 'Controller@control',
            'as'    => 'path_route'
        ]
    );

My controller is setup as follows

function redirectSearchRequest(){

return redirect()->route('path_route', [
        $value1,
        isset($optvalue1) ? $optvalue1 : '',
        isset($optvalue2) ? $optvalue2 : '',
       $value2,
       $value3
    ]);

}


public function control($value1, $iptvalue1 = null, $optvalue2 = null, $value2, $value3)
{
    //process accordingly
}

Now the problem with this is if I had a url which look like http://ift.tt/1VicvnK. It works without any errors but the url can be sometimes without optvlaue1 and optvalue2 and the route returns http://example.com/value1////value2/value3 as expected laravel throws NotFoundHttpException.

Further more to this problem Option variable are not always present but when they are they should be exactly like how the route is set. I cannot change the order around :(.

Hopefully I am clear enough. Cheers for you help.
