How does spanning tree prevent loops

WebJul 3, 2024 · Spanning-tree protocol (STP) is a network protection protocol that allows for setting up loop-free topology for Ethernet networks. The purpose of spanning-tree protocol is to prevent layer-2 or switch loops. Switches forward Ethernet frames based on the destination MAC address. Broadcast frames are sent to all switch ports in the network. WebThe Spanning Tree Protocol is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include backup links providing fault tolerance if an active link fails. As the name suggests, STP …

This protocol is not part of the spanning tree toolkit but it does help us to prevent loops. Simply said UDLD is a layer 2 protocol that works like a keepalive mechanism. WebMay 14, 2013 · Spanning Tree is designed to prevent loops from bringing down your network. It does this by detecting a loop in the topology and will actively block traffic over one or more of the links if a loop is detected. This takes some thought to do right and can be different per VLAN depending on which version of STP you are running.

WebNov 29, 2024 · How does Spanning Tree Protocol Stop Broadcasts Storms and Loops?
