I downloaded this Rspec by clicking on View -> Preview Request Document and then on the next screen click on the Download button. See screenshots below:

Getting the Request Rspec

Download Rspec

The Rspec itself is here. If you know a little bit about XML, you can read and understand this Rspec specially if you keen the network picture handy to cross reference.

Go ahead and remove the tag <history:slice_history….> and its content to get the rpec below. If you look closely, you will know how to add nodes, interfaces and connections in your own network. You will get this file.
