Bridging Example Two (Advanced Bridging):

This example shows how two pairs of XL-12000S units connect two LANs in separate buildings. It shows the best use of the Spanning Tree Protocol (STP) by creating redundant loops in the network. This way if one link becomes unavailable, STP uses the other path to reach the destination. This configuration is ideal when network avail- ability is critical.
