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.
