12. Protocol STP which ensures the existence of a loop free topology in networks that contain any arrangement of devices STP produces a logical tree topology to ensure that a single path exists between any two end stations on an interconnected network STP also provides a high degree of fault tolerance It allows the network to automatically reconfigure the spanning tree topology if there is a bridge or data path failure Multiple paths to a destination can be good as in the case of using secondary paths to provide redundant links in the event of problems with the primary link It can also lead to bad network performance when problems arise from having more than one path STP allows for redundancy without the performance problems How the STP Topology Stabilizes The switch software incorporates the IEEE 802 1D Spanning Tree Protocol STP to prevent the duplication of paths in an interconnected network 1 When a switch with STP enabled starts up it assumes that it is the Root Bridge and puts all of its external ports into listening mode The switch then sends a configuration BPDU listing its bridge ID as being the Root Bridge ID MAC address and priority on all its external ports 2 As each switch port receives a configuration BPDU the switch compares the Root Bridge information in the BPDU to its current Root Bridge information If the bridge priority or MAC address Root Bridge information in the BPDU supersedes the switch s cur
