Today I’ll offer a pretty comprehensive CCNA-level lab that gives us a backdrop to then discuss Spanning Tree Protocol (STP) in a 2-switch topology.

This blog post is simply an index page to the recent blog postings about the pros and cons of using a two switch topology to experiment with and learn about Spanning Tree Protocol (STP).

The site consists of 10 HP ProCurve 2650 network switches, with pretty much default configurations. I understand that spanning-tree protocol can be enabled to detect and address loops.

Much googling ensues and then I realize our little cisco switch has decided there is a spanning tree issue and has blocked the port. I disable spanning tree on that one vlan and the link unblocks ...
