Cisco and Juniper Spanning Tree Interoperability Testing

This lab setup documents the spanning tree protocol behavior between two different vendors namely Cisco & Juniper. My main target was to check if Cisco's PVST protocol will work together with Juniper's VSTP protocol. Luckily it work on this setup as you can see on the spanning tree status screenshots.
