Switching loops cause network to degrade its bandwidth and there is huge packet loss.
It is because ARP (Address Resolution Protocol) and ICMP (Internet Control Message Protocol) packets travel in network endlessly and are even multiplied with time.
One physical indication of this problem is that status leds on switch show abnormal enhanced activity by blinking continuously.
This chokes network bandwidth and these is very less bandwidth available for legitimate traffic.
Work around solution to solve switching loops problem is to enable STP (Spanning Tree Protocol) on switches.
In this tutorial we will create a switching loop and solve it through STP.
