Description

Multiple active paths between switches can cause loops in the network topology. This can cause duplication of frames being forwarded. To prevent loops while providing path redundancy, you can use Spanning Tree Protocol (STP). One limitation of the traditional Spanning Tree Protocol (STP; IEEE 802.1D) is the convergence delay after a topology change. In response, several enhancements were made to improve this convergence time by adding specific Cisco features to the original 802.1D protocol, and by creating new protocols that are faster or more efficient.
This course explores the various enhancements to STP and explains how to implement and configure the original Spanning Tree Protocol, and its Cisco enhancements, Per VLAN Rapid Spanning-Tree Plus (PVRST+) and Multiple Spanning-Tree (MST).
