+==== Two Switches with Single Link ====
+For what we do with our systems, there are generally two data switches between devices, with a link between them (per VLAN) which looks like this diagram below:
+\\
+\\
+{{ :stp_004.png?700 |}}
+\\
+In this example, we can see just a single link from Switch A to Switch B. This means that there cannot be any Loops, so STP would not be required here (although it is worth remember that STP in some form runs on a Cisco be default).
+\\
+\\
+Remember this Statement regarding STP - //**When a switch receives a broadcast message, that switch will forward that message out of every interface on that switch, except the one it was received on.
+**//
+\\
+\\
+Having STP running is not going to cause any issues, and in fact as a safety measure is still quite good (who knows who might bridge the switches with a second cable).
