Lesson 4 — MSTP Configuration
Introduction
You have learned that MSTP was designed to improve the spanning tree protocol's
support for VLANs. You have also learned that MSTP allows you to create multiple
instances of STP and assign specific VLANs to each instance. In the network below,
for example, two instances have been created: One instance for VLAN 10 and one
instance for VLAN 20.
In this lesson, you will learn more about the MSTP convergence process, using these
two instances as examples.
Note
In this figure, two lines are used to indicate that traffic from two VLANs is being
transmitted over the same cable.
