osi-igrp ? ?

Hi, am studying for my ccna.
I was undertaking a lab where you had to configure igrp on a router. Upon entering the following

GAD(config)#router igrp 101

I got an error saying the protocol was not available, after listing the avialable options by running the 'router ?' command i found that igrp was not in the options, instead this was ....

osi-igrp - igrp for osi networks

I tried typing this in instead but it still wouldnt work.
What is osi-igrp ?
Why havnt i got igrp on my router (ios 12.3)

Regards

Damien

Your IOS doesn't have support for IGRP.
