LISP is a networking technology that has been searching for a relevant problem for a decade and a half (the LISP IETF working group started in the spring of 2009). Initially, I was cautiously optimistic. However, as LISP pivoted from an IPv6-over-IPv4 solution to a multihoming solution, then VM mobility and IP endpoint mobility solution, until it finally landed in Cisco Campus BU as the foundational technology of Software-Defined Access, I lost all hope.
