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...
