Section 10.3

visited network using its original EID, then LISP will need to perform a route-
returnability check on the new EID-RLOC mapping for that EID.

What is a "route-returnability check"?

loss for the entire system. Heuristics can be added to LISP to reduce the number of
mapping changes required and to reduce the delay

This sounds like an assertion.

per mapping change. Also IP mobility can be modified to require fewer mapping
changes. In order to increase overall system performance, there may be a need to
reduce the optimization of one area in order to place fewer demands on another.

This would appear to be a tacit admission that LISP has a problem with IP mobility (and would therefore like IP mobility to go away). More of the same a few paragraphs down:

Mobile IP packet exchange is designed for an environment in which all routing
information is disseminated before packets can be forwarded. In order to allow the
Internet to grow to support expected future use, we are moving to an environment
where some information may have to be obtained after packets are in flight.
Modifications to IP mobility should be considered in order to optimize the
behavior of the overall system. Anything which decreases the number of new
EID- RLOC mappings needed when a node moves, or maintains the validity of an
EID- RLOC mapping for a longer time, is useful.
