    spanning tree port priority ?

    SUP

      IN this network diagram R3 is root switch and in switch R1 f1/0 is root port and f1/1 is in blocking state.

      Now if I want to make port f1/1 in switch R1 as root port I have to change (lower) the port priority of f1/1 on switch R2.

       

      why changing the port priority of f1/1 on switch R2 only  doesn'tmake it root port ?

       

      why it is calculating the port priority of R2 .
