I think you should seriously re-consider using rp_filter on a router.
rp_filter is one of the most expensive features in modern routers, you should only use it, if PPS performance is not important. If PPS performance is important, ACL is much faster. ACL is also applicable to more scenarios, such as BGP customers.
How much performance impact should we expect with uRPF? Thanks. -- Make input easy to proofread. - The Elements of Programming Style (Kernighan & Plauger)
