uRPF loose mode configuration on an ASA 5585x

[Scott Sams]

we need to enable uRPF on a Cisco ASA 5585x but looking at the documentation I cannot determine if it runs in loose or strict mode.  for IOS devices, there is the option allow-default that indicates loose mode.  our ASAs have only a default route to their gateway so i need to ensure that any network that is NOT in the routing table will route.  i only want to drop traffic that we specify to a null destination.

thanks

Hello Scott,

On the ASA appliances you will be running strict mode, there is no such a way to support Loose mode.
