Understanding rapid spanning tree protocol
WebThis chapter describes how to configure the Cisco implementation of the IEEE 802.1W Rapid Spanning Tree Protocol (RSTP) and the IEEE 802.1S Multiple STP (MSTP) on your switch. To use the features described in this chapter, you must have the enhanced software image (EI) installed on your switch. RSTP provides rapid convergence of the spanning tree. Web17 Feb 2024 · Rapid STP is a faster protocol than the old version and its purpose in both protocols is to maintain the continuity of the network by preventing loops on the network. …

WebRapid spanning-tree is not a revolution of the original spanning-tree but an evolution. Behind the scenes some things have been changed to speed up the process, … WebAnother version of spanning-tree is able to calculate a topology for each VLAN. This version is called PVST (Per VLAN Spanning-Tree) and it’s the default on Cisco switches. Beginning from Cisco IOS 15.2 (4)E release, the STP default mode is Rapid PVST+ Let’s look at an example where we have three switches and two VLANs.
