you can't if its a valid internet address...can you?
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?
but that isnt the case here is it...some of ur internal core routers may not have every router running bgp, so what do u do for such scenarios..u default route it to a bgp router....im missing your point.....
"loose" RPF on routers without full tables makes little sense. you choose where to filter carefully and avoid the pitfalls you keep raising... marty -- "No GUI for you! Use lynx!!!, Come back, One year!" /avant
