Spanning Tree Protocol
The Quick Definition: Spanning Tree Protocol (STP) is used to prevent Layer 2 loops, commonly known as broadcast storms, from disrupting local area networks. STP virtually disconnects redundant links to prevent loops from occurring.
If you’re tasked with managing bridges and switches, you’ll probably encounter spanning tree protocol (STP) during your configurations. STP is used to configure backup connections when linking between two bridges or switches fails. It provides the most efficient way to forward information between LAN segments, reducing performance issues — without losing redundancy.
