Almost. Suggest changing Brian's wording slightly as follows: "Encapsulation increases the amount of overhead associated with each packet. For LISP, this added overhead decreases the effective end-to-end path MTU." Reason is that this statement is true for LISP, but not necessarily true for all other tunnel types.
