Excellent. I was having the same problem.

Well, seems like a little presure can sometimes help.
BTW, I have not received any post from the list since 2002/7/2 ~12:00.
Ok, I finally found what was going on. It was the COST of the DDR link
that was changing when the interface changed from up to up (spoofing).
Yes, the cost was set to auto, and somehow the bandwidth changed, that
changed the cost, and that forced a LSU.
So just put an "ip ospf cost xxx" and you are ok.
HTH, it sure helps me :-)
