I just upgraded one of our 7206 routers from 12.2(18)S to 12.2(25)S and Fast Switching is now disabled. I tried the command ip route-cache on the interface but Fast Switching is disabled when you do show ip int command. Fast Switching was enabled on 12.2(18)S. I have another router to upgrade but I'm not going to upgrade it until I get this problem figured out. Any help will be appreciated. Thanks.
