Multiple Instance Spanning-Tree Operation
Overview
The switches covered in this guide, use the IEEE 802.1s Multiple Spanning
Tree Protocol (MSTP) standard.
MSTP Features
Without spanning tree, having more than one active path between a pair of
nodes causes loops in the network, which can result in duplication of mes-
sages, leading to a “broadcast storm” that can bring down the network.
