Let me know if it would fine to keep the reference to 6830 in Informative, otherwise no problem in removing it.

IMO you do not need a reference to 6830, you can modify the text being generic. The problem of stale mapping arise any long TTL.
 Instead of :

As per Section 6.6.1 of [RFC6830], the default setting for an EID-to-
   RLOC mapping TTL in the cache is 24 hours.  Upon the expiry of that
   TTL, the xTR checks if these entries are being used and removes any
   entry that is not being used.  The problem with this 24-hour Map-
   Cache TTL is that (in the absence of PubSub) if a mapp


You can put:

  EID-to-RLOC mappings can have very long TTL, in the order of several hours..  Upon the expiry of that
   TTL, the xTR checks if these entries are being used and removes any
   entry that is not being used.  The problem with several hours-long Map-
   Cache TTL is that (in the absence of PubSub) if a mapp


What do you think?
