If STP is enabled, it will detect duplicate paths and prevent, or block, one of the paths from forwarding
traffic. In the following example, STP determined that traffic from LAN segment 2 to LAN segment 1
should flow through bridges C and A since this path has a greater bandwidth and is therefore more
efficient.
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.
