Whenever we connect three or more Layer 2 devices there are many issues like Broadcast storms, Mac instability, Bridge multiple frame transmission, and Switched Networks. So, to eliminate these problems IEEE 802.1D protocol was implemented in Layer 2 devices. It not only helps in reducing the above-mentioned problems but also combines two links connected to a single device to remove looping and increase load balancing so called Ether Channel. STP reduces the burden of network engineers by simply removing loops and automatically converging when network topology changes which helps in avoiding loops.
