+1 in my experience uRPF get’s enabled, breaks something or causes confusion (usually related to multi-homing) and then get’s disabled. On Feb 28, 2014, at 11:49 AM, Christopher Morrow <morrowc.lists@gmail.com> wrote:

If you have uRPF enabled on all your access routers then you can configure routing policy such that advertising a route for a specific host system will trigger uRPF to drop the traffic at the first hop, in hardware.
note that 'in hardware' is dependent upon the model used... note that stuffing 2k (or 5 or 10 or...) extra routes into your edge device could make it super unhappy.
your points are valid for your designed network... they may not work everywhere. making the features you point out work better or be more widely known seems like a great idea though :)
