RE: urpf

Thanks Marko, that sounds like loose mode. Is there a difference in loose and feasible modes?

Feasible mode accepts the packet if the interface is one of the
possible destinations (say in a case of load sharing), otherwise the
packet is dropped. AFAIK, you cannot configure it in IOS 12.4. I'm not
sure about 15.x and/or IOS XR.
