Hi All,

Thanks for all your responses, really appreciated. I tried implement 'area 0
auth mess' under r1's ospf router configuration(as suggested by all of you),
and everything seems to be working. However, when I do 'sh ip os v' on r1
and r2, it says that 'no key is configured', any ideas? Following are the
configurations for r1 and r2. Can someone tell me if the configurations are
correct?

Thanks again.

I am taking the lab on 2/12 in San Jose, anyone is taking the exam on the
same date?

r1:
interface Loopback0
 ip address 132.1.1.1 255.255.255.0
interface Serial0
 ip address 132.1.15.1 255.255.255.252
 clockrate 2000000
router ospf 1
 network 132.1.1.1 0.0.0.0 area 4
 network 132.1.15.1 0.0.0.0 area 3
 area 0 authentication message-digest
 area 3 virtual-link 132.1.5.5

r1#sh ip os v
