Router OSPF config help

[TheVinesKid]

I'm doing a simple lab, 3 routers connected through a switch configured with OSPF. The point is DR/BDR election.
I've followed every direction in the lab, to the tooth.
First the DR/BDR was elected through the highest IP, now I've added loopback addresses to change the DR, and I need to get the routers to see the change.
So I've entered the command:
R1#clear ip ospf 1 process

and I ALWAYS get the invalid input, with the ^ pointing to the o in ospf.

I've tried it w/o the AS also.
I've tried it on all 3 routers.
Nothing works.
I know I can just issue the reload command, but I want to know why this isn't working. I'm doing EXACTLY what the thing says to do.

I'm gonna go freakin crazy here...
Please, someone help me!

Which IOS are you using?

Your lab must be using IOS 12.2 or below. It's a bug that thinks there are duplicate router ids. Not your fault. Upgrade the code on the router in the lab if you can.
