Or may be:

Mapping updates, and their corresponding Map Version Number MUST be managed so
that  a very old version number will not be confused as a new version number 
(because of the circular numbering space). To this end simple measures can be taken, like 
Updating a mapping only when all active traffic is using the latest version, or waiting sufficient time
to be sure that mapping in LISP caches expire, which means waiting at least as much as the mapping Time-To-Live (as defined in 6833bis)   

Any preference?
