What happened to IGRP ???

Comments
Router(config)#router igrp 20
Router(config-router)#network [destination net] [subnetmask] [next hop]
After configuring and saving you can try :-
Router#show ip route (check if IGRP is installed in the routing table)
Router#show ip protocols (check for IGRP in routing protocols I-IGRP )
Hope that helps.
It's true, cisco IOS 12.3 doesn't support IGRP
If you're going to replace the IOS I would go for 12.2T, IP Plus.
When you're using the router for you CCNA, you can configure DHCP and NAT on it. Not all IOS software supports DHCP ...
