Earl's answer is probably the one you're looking for if we understand your
requirement correctly. But if you aren't told you must only have one
network entry, I agree with the other person that said to use the ip
address off of the interface and 0.0.0.0 wildcard bits, as in:
network 172.168.1.1 0.0.0.0 area 0
There's less chance for error and it's obvious if the proctor changes it
because the ip address will always be the ip address from the interface
and the wildcard bits are always 0.0.0.0. This is also a recommended
way to do it in a production network *IF* you don't have a lot of
interfaces, it makes troubleshooting far easier.
By the way, why such a huge network for the loopback, why not a /24
or a /30 or /32? It's going to be advertised as a /32 anyway if you don't
change the ospf network type to something other than the default.
