In my router,there is a null router-map in interface,I don't know if there is some specify function or just somebody forget to delete it.
any comments are appreciated! thanks!

ip address 10.x.x.x 255.255.255.0
ip policy route-map null_policy_route
speed 100

I believe somebody forget to delete it, as you have suggested.
