STP Root Port Election..

Hi all,

When electing the root port, what criteria does a switch look at before making
its decision?

My understanding is (in order);

1. Lowest Cost to the root bridge
2.Lowert port address (port priority : port number) --> Is this of the sender
or the receiving root bridge?
3.Lowest bridge ID

Is my understanding correct?

Also, how does a switch decide on its DESIGNATED port? Is this the lowest
bridge ID?

thanks,

Jit
