RFC 3162 Section 2.3 states about Framed-IPv6-Prefix:

"     This Attribute indicates an IPv6 prefix (and corresponding route)
      to be configured for the user. "

For Framed-IPv6-Route, RFC 3162, Section 2.5 states: 

"     This Attribute provides routing information to be configured for
      the user on the NAS.  It is used in the Access-Accept packet and
      can appear multiple times."

RFC 2865, Section 5.10 describes Framed-Routing:

"     This Attribute indicates the routing method for the user, when the
      user is a router to a network.  It is only used in Access-Accept
      packets."

Based on this, I think Framed-IPv6-Prefix causes a route to be added 
on the NAS and advertised to the user via Router Advertisement, but not 
via routing packets (e.g. RIPv2) unless indicated in Framed-Routing.
