Hi Carlos, 

    TE tunnels provide no real reservation, it is just in the control plane,
not in the forwarding plane. There are no specific buffer space assigned to
that tunnel which guarantees anything, it is just that now you have
2000-500=1500 left for new "reservations".

   Regards.
   Javier.
