Y What happens if a link failure is detected As shown in next figure the STP process reconfigures the network so that traffic from LAN segment 2 flows through Bridge B LAN 1 STP will determine which path between each bridged segment is most efficient and then assign a specific reference point on the network When the most efficient path has been identified the other paths are blocked In the above 3 figures STP first determined that the path through Bridge C was the most efficient and as a result blocked the path through Bridge B After the failure of Bridge C STP re evaluated the situation and opened the path through Bridge B 3 28 PT 7728 User s Manual Featured Functions How STP Works When enabled STP determines the most appropriate path for traffic through a network The method is described below STP Requirements Before STP can configure the network the system must satisfy the following requirements e Communication must be established between all bridges This communication is carried out using Bridge Protocol Data Units BPDUs which are transmitted in packets with a known multicast address e Fach bridge must have a Bridge Identifier that specifies which bridge acts as the central reference point or Root Bridge for the STP system Bridges with a lower Bridge Identifier are more likely to be designated as the Root Bridge The Bridge Identifier is calculated using the MAC address of the bridge a
