ip route-cache and load balancing

I am working on RIP and IGRP. As cisco, the routes will load balancing per
packet if we issue no ip route-cache in interface otherwise, they will load
balancing per destination. I try issuing no ip cache and it works as sell,
loading share per packet. then I put ip route-cache, even restart all
routers, it still loading share per packet. I show ip cache and see nothing.
What is happen with IOS? anyone have experience with this problem?

How do you know it's doing per-packet load sharing? If you're testing
with ping or traceroute on the router itself, that is not a good test.
Traffic originated on the router is always process-switched, the
route-cache is only used for packets being forwarded.

Also, if you have CEF enabled on the router, its "ip load-sharing
per-packet" command may take precedence.
