MY_Router class is extending CI_Router.

Can some one guide me in this regards.

CodeIgniter loads your MY_Router class automatically if you put it in application/core for 2.0, otherwise application/library for 17.x.

If you wish to call your method from the controller, just use $this->router->foo();
