Hi,
If you "clear ip ospf pro", will the Adjacency State still got "Full"? I
have tested in my scenario that even I cannot see this row after OSPF
reload.
Thx,

I was under the impression that if A0 was using authentication, that the
virtual link themselves would need to use that same key. It is even
explained in the following link:
http://www.cisco.com/warp/public/104/27.html
The scenario that I have is such:
(area50)R5(area10)R6(area0)R8
The config for R6:!
interface Serial0.2 point-to-point (to R5)
ip address 150.4.10.9 255.255.255.248
frame-relay interface-dlci 605
interface Serial1 (to R8)
ip address 150.4.68.1 255.255.255.252
encapsulation ppp
ip ospf message-digest-key 1 md5 cisco
clockrate 250000

router ospf 1

R5 config:

ip address 150.4.10.10 255.255.255.248
frame-relay interface-dlci 506
router ospf 1

area 10 virtual-link 150.4.6.6
network 150.4.10.8 0.0.0.7 area 10
network 150.4.50.0 0.0.0.255 area 50

O IA 150.4.14.0/24 [110/129] via 150.4.10.9, 00:07:41, Serial0.1
O 150.4.68.0/30 [110/128] via 150.4.10.9, 00:07:41, Serial0.1
As you can see, R5 is getting the routes in the OSPF domain without the
auth-key defined. Does this contradict the link provided above from cisco?
