[nsp] routing table

hi, need some advise on simple routing..

 ip route xx yy zz

suppose I have a static route with the next hop specified as a pt-to-pt IP address (zz) on the same router.  If the interface for that pt-to-pt IP address is down, should the static route (for xx) still take effect, when the router learn the next hop (zz) as /16 or other prefix length, instead of /30.  The longer prefixes is advertised (OSPF) by other routers which is a few hops away.

Realise different vendors do it differently. Some drop, some don't.  Who is correct??  

Anyone knows any RFC on the selection/dropping of routes?
