that's because the virtual-link is considered an extension from area 0, and
so it has to have the same authentication type as area 0; in this case,
clear text.
The transit area authentication type does not affect the virtual-link
authentication type, that has to be same as the area 0.

Subject: OSPF Virtual-LInk Authentication
Date: Thu, 22 May 2003 17:38:19 +0800
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...
