MiniEdit is a graphical environment to create Software-Defined Networks. Once you have designed a network visually, you may export the level 2 script as an *.mn file, which can later be opened and modified, or executed by MiniEdit. The designed network can also be saved as a Python script that can be run as any other Mininet emulation (that is, a Python program emulating networks with Mininet). Thus, MiniEdit lets you design reproducible network designs that can be executed in Python as a Mininet emulation, or emulated directly through MiniEdit (which in turn invokes Mininet for the backend emulation in a console).

In this recipe, we created a variant of leaf-spine topology for this recipe with the help of MiniEdit and saved it as .py and .mn, which we later executed. As you may notice, properties of hosts, switches, links, and controllers may be specified through the GUI of MiniEdit.
