I have to wonder if it would have. Unless you have some kind of route visibility collecting took, or a bunch of simulated traffic sufficient to pop the CPU on the vMX that represented atl01, it would all appear to work. I wonder if you could generate traffic, and scrape snmp counters as a proxy?

Or some kind of tool that processes the resultant routing tables to generate some kind of "route usage" for every given link and device, maybe even feed it with a table of expected traffic to given destinations.
