Here is the logical and physical view:
Setting-up a virtual lab
Downloading BSD Router Project images
Download BSDRP serial image (prevent to have to use an X display) on Sourceforge.
Download Lab scripts
More information on these BSDRP lab scripts available on How to build a BSDRP router lab.
Start the lab with full-meshed 5 routers and one shared LAN, on this example using bhyve lab script on FreeBSD:

Final testing
From R1, ping the server R4 (88.88.88.4):
