For the following visio diagram, help me design a diagram that does the following:

1. Duplicate the entire infrastructure and mirror for a second backup DC, including the workstation access layer, all on the same diagram

2. Make a module out of the existing network. The main site may need smaller modules to identify repeated elements.

3. Connect the two modularized networks together using a private Telco WAN connection and a backup VPN connection using the current ISP infrastructure. Add the appropriate devices to support this connectivity. Include the network layering.

4. Indicate where OSPF and BGP could be used at each location and where the protocols will meet.

5. Indicate VLANs where required to reduce traffic.

6. Indicate what is required to isolate the access layer PCs while maintaining the mirror.

7. Indicate global connection to Office365.
