You can't.  The VpnService.Builder class (or the adapter in
CharonVpnService) is just that, a builder.  Once the TUN device has been
created (by calling establish()) calls to any of the add... methods are
ignore (the adapter internally creates a new instance of the Builder
class so there the routes are stored for the next call to establish()).

> Could you please suggest us the way to add route on tun0 interface after

You would have to store all the information added to the previous
Builder object and then create a new TUN device when you added your routes.
