Yes, we all love less state, I won't argue that. But it's the same question that is being asked less and less with each passing year - what scales better in 2020, OSPF or IS-IS. That is becoming less relevant as control planes keep getting faster and cheaper.
I don't think it ever was relevant.
In 99% of cases, there are cases however where supporting 1M+ routes in IGP is one of the viable options to consider, or running multi-100k of LSPs through a core node... But these are core MPLS networks that have no boundaries cause these literally wrap around the globe, and access to custom code. adam
