Hmmm are you sure about this? I think you should put the authentication on
the "virtual link" in your example and NOT on the physical s0 as I
understand. I just tried it in fact!
OK about my first question, this is killing me now as one day it works and
the other day it kept complaining. Basically on my hub router I could only
see one of the authenticated virtual links up at a time. Right now they'e
both us after I reloaded both spoke ABRs. Is using 2 parallel links causing
some loop of some kind?? I know it sounds dumb but this thing has been
bothering me for almost 2 years now!!!! Really.
Thanks again
Tarek

Tarek,
I could only guess on the answer to your first question, so I'll let someone
else answer. On your second question, "If area 0 is authenticated, do I
have to put authentication on the virtual link?", the answer is yes. For
example:
Router A (has area 0 and area 2)
Router B (has area 2 and area 3):
router ospf 64
network 192.168.1.2 0.0.0.0 area 2
network 172.48.3.2 0.0.0.0 area 3
area 2 virtual-link 192.168.1.1
area 0 authentication message-digest
interface serial 0
ip ospf message-digest-key 1 md5 KEY1
HTH, Kym
