Yes. Path enumeration when you use mult-tier Clos topologies within a PoP causes you many, many problem.

Okay, got you. I thought you were running into these problems on the "usual suspect" platforms. Yes, commodity hardware certainly has a number of trade-offs for the cost benefit. We've been evaluating this path since 2013, and for our use-case, it will actually make less sense because we are more large capacity, small footprint, i.e., typical network service provider. If we were a cloud provider operating at scale in several data centres, our current model of running Cisco's, Juniper's, Arista's, e.t.c., may not necessarily be the right choice in 2020, particularly in the edge.
