|   There is an existing mechanism to convey information from router to
|   host, the router advertisements; it can be used, at a 
|   minimum, to prefer
|   the source prefixes that correspond to functional providers 
|   over those
|   for which connectivity has been lost; it is easy to use 
|   this mechanism
|   in a single link network; using it in a more complex 
|   network requires
|   exchange of information between the site routers. If that 
|   mechanism is
|   not sufficient, nothing prevents us from designing a better one,
|   possibly some variation of ICMP Redirect between site exit 
|   routers and
|   host on the site.


True.  When designing, please remember that unauthenticated
redirects would be a huge security hole.
