The Spanning Tree Protocol (STP) is enabled by default, so we can go ahead and verify using the show spanning-tree command on each switch. Notice that all switches have a default priority of 32768. My network chose the 871W router as the root bridge by default. The best way to optimize the Layer 2 network is to manually assign the core switch as the root bridge, which is SW1 for this case.
