I finally had an opportunity attempt implementing uRPF.  I made my VRF 
applied to interfaces tried to enable uRPF and...

% ip verify configuration not supported on interface Fa0/23
 - verification not supported by hardware


It's clear this feature is a tease from Cisco. I haven't been able to 
find anyone or any real world reference to uRPF on the ME3400.

I'm going to ask the list now.  Has anyone gotten this feature to work? 
If so please reply with any configuration if you can.

Thanks
