Network Configuration Examples Chapter 1 Overview Point-to-Multipoint Bridging In a point-to-multipoint configuration, two or more non-root bridges associate to a root bridge. Up to 17 non-root bridges can associate to a root bridge, but the non-root bridges must share the available bandwidth. See Chapter 2, "Configuring the Bridge for the First Time," for instructions on initial bridge setup. Figure 1-2 shows bridges in a point-to-multipoint configuration. Figure 1-2 Point-to-Multipoint Bridge Configuration Root Bridge Switch Non-Root Bridge Non-Root Bridge Switch Switch 88905 Non-Root Bridge Switch Note If your bridges connect one or more large, flat networks (a network containing more than 256 users on the same subnet) we recommend that you use a router to connect the bridge to the large, flat network. Redundant Bridging You can set up two pairs of bridges to add redundancy or load balancing to your bridge link. The bridges must use non-adjacent, non-overlapping radio channels to prevent interference, and they must use Spanning Tree Protocol (STP) to prevent bridge loops. See Chapter 8, "Configuring Spanning Tree Protocol," for instructions on configuring STP. Note STP is disabled by default.
