Description and examples of PVST+ operations

This blog entry will be about Spanning-Tree protocol. Whenever I wanted to know how exactly STP would behave in specific situations and how long it would take for network to reconverge - it appears that I needed to review some aspects of STP operations or simply I did not understand the subject good enough. I decided to make summary from my findings and tests, so the next time I will be in doubt about my understanding of STP - it will be easier to refresh the topic.

At first basic operations of STP will be briefly described and then specific scenarios will be presented.

Cisco PVST+ version of Spanning Tree Protocol is covered in this article.
