think of it this way:
use the ip ospf message-digest-key command to set the MD5 password to
use for authentication on the interface level.
After you have configured the key, you enable it under the ospf router
process.
router ospf 10
area 0 aut mess
It is similar to access-list configuration. First you define what
will be allowed, then you apply it. The concept is similar here.
first define the md5 key and then apply it to an area.
The example I used uses MD5 authentication. You could also use clear
text passwords, using the ip ospf authentication-key command. Then
you apply it to ospf using the area 0 authentication command.
Hope this helps

Subject: OSPF Authentication
Could any one tell me how to use ospf authentication?
There is a command "ip ospf authentication-key" and "ip ospf
message-digest-key" in interface configuration mode. There is another
command "area x authentication [message-digest]". I want to know what
is the relationship between these two commands.
Document CD said that "ip ospf authentication-key" is used with "area
x authentication" and "ip ospf message-digest-key" is used with "area
x authentication message-digest-key". But I found that "ip ospf
authentication-key" can be used with "area x authentication
message-digest-key" and "ip ospf message-digest-key" can be used with
"area x authentication".
So could anyone tell me what is the relationship with these two
commands on earth.
------------------
I find that the authentication type is identified by "area x authen"
command. ???
