Hi Scott

I have just seen your question about me using the letters CS returned to me today.

CS was me using this acronym to express my feeling for requesting help from this community.

It simply stands for 'CS' = Community Support

I still was not sure if it was possible for me to know if there are "Virtual Routers" that can be used in my virtual network that I am studying. 

If this is possible, I would presume that if there was applications for this, then I expect there would be applications for other devices like Firewalls, Access Points, Switches and the likes as in the Cisco Packet Tracer!
