router rip command on Cisco IOS 11.x

in CCNA & CCENT
Guys, I am trying to run router rip on my cisco 2500 router which is running IOS 11.x, but it doesn't recognize it for some reason.
from enable mode:
conf t
router-config # router rip
It has worked on my other two routers in the network which are both running 12.x, but the one running 11.x doesn't like it.
Thanks in advance.

You didn't show us any terminal output -- so are you sure you're in config mode?
What does router ? show you (assuming you are in config mode)?
I checked both routers and the rip command works.

I found version 10.0 info, but nothing on 9.0? and earlier...maybe 10.0 was the beginning? If so, why did they choose 10?
Good info!!! Thanks...
