It doesn't seem to be working for me. What version of IOS does this new feature show up in? Why hasn't it been mentioned before? Or is this not similar enough to be usable to block smurf and other forgery? Danny McPherson writes...
Cisoc already has a feature similar to this, "ip verify unicast reverse-path". -dannyDanny McPherson writes...ingress filtering .. that's a novel idea :-)"smart" ingress filtering, as opposed to hard coded filtering, which is already done a lot. It would come at some costs, as every packet would have to have 2 routing lookups done for it, one of which must return or compare against all routes, not just the best route.
