I am confuse with the term designated and root port.
"The designated port is the port that is the single interface to forward traffic to the root bridge"
"The root port represent a switch's lowest-cost path to the root bridge"
1) Can i say all ports from root bridge port are root ports since they are the lowest-cost path to the root bridge?
2) Say Switch A is the root bridge and Switch B and C is connected through port 1 to Switch A. Can i say port 1 of Switch B and C is a designated port since it is the single interface to forward to the root bridge?
3) Can the root bridge have designated port?
