If you are sending to something connected to the root switch, or a switch in the path to the root switch, then it is on the path with the best cost. You should realize that the best cost is toward the root switch. In your diagram, if your connection from one switch to the root switch was a very high cost, that path may be blocked, and the connection between the bottom switches would not be blocked. This would also be a loop-free path. The entire point of STP is to eliminate all the possible loops. Having layer-2 loops will almost instantly kill your network. | |
