Figure 3-5, 3-14

During production the diagrams are often redrawn. In this case there were two changes that are inconsistent with the text discussion and other diagrams. 1 � Figure 3-5 depicts Switch 2 on top and Switch 3 on the bottom. These should be reversed. 2 � Figure 3-14 depicts BPDUs flowing to the root bridge which is just all kinds of wrong. The arrow between switch 2 and 3 should be going the other way.
