Zend-framework 1.12 module: links always lead to default module - zend-framework

Question

I created ZendFramework 1.12 applications with modules.
The idea was to have versions of the API in modules, with RESTfull paths.
The default module was V1, and now when I am trying to create v1s1 module, all links still lead to V1.
Can anybody push me in the right direction how to solve this?
MORE DETAILS
This is the code I have to use modules.
application.ini
resources.frontController.moduleDirectory = APPLICATION_PATH "/modules"
resources.frontController.defaultModule = "v1"
resources.modules[] =
v1.boostrap.path = APPLICATION_PATH "/modules/v1/Bootstrap.php"
resources.frontController.plugins.putHandler = Zend_Controller_Plugin_PutHandler
routes.rest.type = Zend_Rest_Route
routes.rest.defaults.module = v1
Main Bootstrap.php:
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
protected function _initAppAutoload()
{
$autoloader = new Zend_Application_Module_Autoloader(array(
'namespace' => 'V1s1',
'basePath' => APPLICATION_PATH . '/modules/v1s1',
));
$autoloader->addResourceType('model', 'models', 'Model');
return $autoloader;
}
}
V1 Bootstrap.php:
class V1_Bootstrap extends Zend_Application_Module_Bootstrap
{
protected $_moduleName = "v1";
protected function _initAutoload()
{
// Add autoloader empty namespace
$autoLoader = Zend_Loader_Autoloader::getInstance();
$autoLoader->registerNamespace('v1_');
return $autoLoader;
}
protected function _initResourceLoader()
{
Zend_Controller_Action_HelperBroker::addPath(APPLICATION_PATH . '/modules/v1/controllers/helpers');
}
public function _initRouts()
{
$front = Zend_Controller_Front::getInstance();
$restRoute = new Zend_Rest_Route($front, array(), $arrayOfControllers));
$front->getRouter()->addRoute('rest', $restRoute);
}
}
Now I need to create module v2, but when I do that, I everything crashes. Link are no longer RESTfull, and every link still leads to the V1 module. V2 module Bootstrap.php is being accessed.
