Jammie,
I agree with Kenneth, you might not notice that you had given a extra key
stroke of ? just to see if any additional parameter exist, but this
will give you a grief while entering the passwords so be aware not just
for ospf authentication you have to take this measure for any similar
instances.
In addition just to let you know that neither Plain text nor MD5 have to
be same throughout the area despite it requires be the same between
neighbors.
Following link will clarify this point
Best wishes,
