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: |
