afaik if these are consistent with other t2/tomahawk/helix switches
they're roughly 200K alpm routes installed or as few as 16K. if you
install selected routes and otherwise default  or this is a peering only
router, that can get you pretty far but it's not a full table by any means.

control plane on the switches mentioned about is 2GB of ram and a dual
core atom, so it's fine more or less for a datacenter TOR. It's not
particularly powerful. I find out particular tooling doesn't run that
well in 4GB any more so your milage may vary.

the supermicro should bear a striking  resemblance to the dell 3048 that
was splayed open here
