Hi,Oliver
    As your said I do,but show ip ospf virtual,as the following:

R2#sh ip os v
Virtual Link OSPF_VL0 to router 202.97.1.1 is up
  Run as demand circuit
  DoNotAge LSA allowed.
  Transit area 1, via interface Serial0.34, Cost of using 64
  Transmit Delay is 1 sec, State POINT_TO_POINT,
  Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
    Hello due in 00:00:01
    Adjacency State FULL (Hello suppressed)
    Index 1/2, retransmission queue length 0, number of retransmission 1
    First 0x0(0)/0x0(0) Next 0x0(0)/0x0(0)
    Last retransmission scan length is 1, maximum is 1
    Last retransmission scan time is 0 msec, maximum is 0 msec
  Simple password authentication enabled
-----------------
I use MD5 authe on VL,but this showed "Simple password authentication enabled", is right?

You need area 0 authentication on R2 as well and take out "area 1
virtual-link 202.97.2.2 authentication message-digest" , you dont need this.

Betreff: OSPF Virtual-LInk Authentication

Hi,everyone
I have a question about OSPF authentication--

AREA 0----R1--AREA 1---R2---AREA 2---R3

poppose the area 0 use clear text authentication, area 1 use MD5.the
following is R1&R2's configuration:
R1:
router-id 202.97.1.1
area 0 authentication
area 1 authentication message-digest
area 1 virtual-link 202.97.2.2 authentication message-digest
area 1 virtual-link 202.97.2.2 message-digest-key 1 md5 cisco
...

R2:
router-id 202.97.2.2
area 1 authentication message-digest
area 1 virtual-link 202.97.1.1 authentication message-digest
area 1 virtual-link 202.97.1.1 message-digest-key 1 md5 cisco
...

when I finished,I found that on R2:
show ip ospf
Area BACKBONE(0)
Number of interfaces in this area is 1
Area has no authentication
my question is: AREA 0 has clear text authe in fact,but on R2 no authe,is
this right? and following i added "area 0 authentication" on R2,then showed
Area BACKBONE(0) has simple password authentication.
I pluzzed...
