LISP is one example of a broad class of encapsulation-based systems that emulate either subsets or switching devices, e.g., including TRILL, 802.1Q-2014, etc., a class I’ve been referring to as recursive routers and is fundamental to network virtualization.

IMO, they’re no more a stop-gap to networking than VM is to memory.

But we’re digressing from the original thread...
