My configuration at the end is no different of what you get when you configure one router at the time, it is just the order of operations that makes it working right away.
It has been a while, but I think I did reload my routers and the neighbor relationship came up again after a while...
But let me try again later, I'll let you know for sure

Subject: Re: Multiple OSPF keys on Hub and Spoke Frame Relay
I had a similar problem..
When I did a debug ip ospf adj i saw that the router only sends out the
latest key id. (e.g. sends out
key 2 and not key 1)
When I tried do configure the same stuff over an ethernet link, the
router sends out both keys.
(key 1 and key 2) Maybe there is a dependency of the ospf network type.
Can you try to configure an ospf broadcast network type over your frame
relay cloud?
Sabrina, what is with your configuration after a reload of the routers??
I guess this can
cause problems...
