WebSpanning-tree is one of the protocols that you must understand as a network engineer and you will encounter it for sure if you decide to face the Cisco CCNA R&S exam. This lesson is an introduction to spanning-tree, you will learn why we need it, how it works and how you can check the spanning-tree topology on your Cisco switches. Webt e The Spanning Tree Protocol ( STP) 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. the song indiana wants me

The need for the Spanning Tree Protocol (STP) arose because switches in local area networks (LANs) are often interconnected using redundant links to improve resilience should one connection fail. However, this connection configuration creates a switching loop resulting in broadcast radiations and MAC table instability. If redundant links are used to connect switches, then switching loop… WebSW3(config)#spanning-tree vlan 1 priority 4096 SW2(config)#interface fa0/19 SW2(config-if)#spanning-tree cost 50.

However, an Ethernet network needs to include loops because they provide redundant paths in case of a link failure. Spanning-tree protocols address both of these issues because they provide link redundancy while simultaneously preventing undesirable loops. myrthengasse hostelWebThere are two kinds of BPDUs for 802.1D Spanning Tree: Configuration BPDU, sent by root bridges to provide information to all switches. TCN (Topology Change Notification), sent by bridges towards the root bridge to notify changes in the topology, such as port up or port down. By default the BPDUs are sent every 2 seconds.
