If STP is enabled, it will detect duplicate paths and prevent, or block, one of them 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 because 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.
