Chapter 2 — Connecting to the Network
A Spanning Tree | Dividing your network into two segments reduces your overall  | 
  | backbone traffic and improve network efficiency, but also intro-  | 
  | duces a certain element of risk: the bridge becomes the sole path  | 
  | between the two segments. If the bridge fails for any reason,  | 
  | devices on different segments will no longer be able to communi-  | 
  | cate with each other.  | 
  | This may not seem serious, but consider the implication if your  | 
  | database server is on one segment and must be accessed by  | 
  | devices on the other segment. Suddenly the stakes are a little  | 
  | higher. Fortunately, by simply installing an additional bridge  | 
  | between the two segments, you can provide a high degree of  | 
  | redundant protection. Such a network configuration would look  | 
  | like this: |
