depends on what you mean by "valid".
- does "valid" = any 32 bit dotted quad?
- does "valid" = any IP not in 1918 space?
- does "valid" = any IP that the routing table has an entry for?
- does "valid" = packets from this IP came in the interface i would send
packets out of to reach that IP?

"loose" RPF on routers without full tables makes little sense. you choose
where to filter carefully and avoid the pitfalls you keep raising...
