Abstract:

   When RFC 6724 was published it defined an address selection algorithm
   along with a default policy table, and noted a number of examples
   where that policy table might benefit from adjustment for specific
   scenarios.  It also noted that it is important for implementations to
   provide a way to change the default policies as more experience is
   gained.  This update draws on several years of such operational
   experience to refine RFC 6724, with emphasis on preference for the
   use of ULA addresses over IPv4 addresses and the addition of
   mandatory support for Rule 5.5.  It also defines the concept of
   "known-local" ULA prefixes and the means by which nodes can identify
   them and insert them into their policy table such that ULA-to-ULA
   communications become preferred over GUA-to-GUA for local use.  The
   update also demotes the preference for 6to4 addresses.  These changes
   to default behavior improve supportability of common use cases,
   including automatic / unmanaged scenarios.  It is recognized that
   some less common deployment scenarios may require explicit
   configuration or custom changes to achieve desired operational
   parameters.
