Indeed there is a contradiction. The end of the section is actually a relic of 
previous versions of the document. 

I would just delete the last paragraph. The plan discussed during the last WG 
meeting was to put a “deadline” at 2020. 

By that time there will be sufficient deployment experience to decide whether 
or not have a permanent allocation (or “renew” the experiment).

LISP does not need such a corralled space. 

There point of the experiment is to understand if by having a dedicated LISP 
EID space any technical benefit can be achieved. 

Since the community seems to be split on this topic the experiment can give the 
answer.

No permanent allocations ;-)

The IETF will decide between 2017 and 2020 what to do afterwards and how to do 
it.

There is no renumbering needed with LISP, it is just about adopting the 
technology.
