How about changing the network type to point-to-multipoint in order to get
rid of the neighbor commands?

upon reboot
I noticed the same thing when I fired up my finished IPExpert OSPF lab
today. I asked the GS list about not being able to set a ospf neighbor two
days ago and the solution was to get the OSPF neighbor command to work you
need to first remove all virutal links and then add the neighbor commands.
If this is the case how would you keep the virtual links up after a
reboot in the real CCIE lab?

Scott Morris explains it like this:
==========================================================================
It's more a feature than a bug. Basically it boils down to confusing OSPF.
If your non-broadcast network is operating FIRST, then you can add
virtual-links. If you try to add VLs before it's operating, you may find
config pieces begin to disappear.
Always check out "show ip ospf interface brief" to make sure you are
really running in non-broadcast or point-to-multipoint-non-broadcast modes
which are the only two that take neighbor commands!
