| In STP, what is the difference between a designated and a root port. I know a root port connects to the root switch. Is a designated port, a port that is not directly connected to the root switch but takes you there evantually?? Thanks a lot, I confused on this | |

| Root port - The port of a bridge that is closest to the root bridge in terms of path cost.
Designated port – For each physical network segment, the bridge with the lowest cost to the root bridge is elected as the designated bridge of the segment. The port of the designated bridge that connects to the network segment is known as the designated port.

| I was taking an online course and it was confusing me but I asked a co-worker and he explained that the designated port goes out from the root switch and the root port goes into, or connects other switches to the root... thank you for replying =] | |

| Remember 1 designated port per segment. Designated ports are always in the foewarding state. | |
