So how do I integrate the new, empty Fabricpath network at the bottom of the page with zero hosts into the network at the top which has 50 locations in multiple states and over 35,000+ ports and operates around the clock ?
Without of course any service interruptions that might drop applications.

Have placed the Cisco and Packetlight equipment at all 3 locations including a location that could provide some add/drop functionality if wanted.  Packetlight provides a friendly GUI interface for management and also by default shows the topology when you first log in as shown below.
