Most of us can't "ip verify unicast reverse-path" our upstreams.
I think you can run it on low/mid-range Cisco routers with IOS 12, as CEF is not 75xx privilege any more, although I have not tested myself.
Routing those networks to nul0 and turning 'ip verify unicastreverse-path'on CEF-enabled Cisco routers does this without CPU load or does not ?
