Hi,
I had this problem, when i configured:
under ospf process both:
area 0 authentication message-digest AND
area X virtual-link a.b.c.d message-digest-key 1 md5 ccie
try to put :
under interface:
ip ospf message-digest-key 1 md5 cisco
and under ospf process:
area 0 authentication message-digest
Please let me know If it help.
Honestly I don't have an explanation of it.

Subject: flapping ospf virtual link over isdn
Hi,
Anyone saw this before? I have virtual link running on
the isdn and cannot keep it quite. If virtual link is
running as demand circuit and DoNotAge is allowed, why
it died like below, which would cause isdn flapping?
