Steve,

        The "authentication" command you are looking for is performed inside th
e
ospf process. You need to use the authentication key at the interface level,
and then in your router process you use the "area x authentication" command
where x is your area number.

        You say that it works without this, but are you sure that it is
authenticated? Maybe you have a neighbor relationship, but it is
unauthenticated. Try mismatching the passwords and see if they still form a
neighbor relationship. I think you will find that they still will, until you
use the area based authentication command.

Troy,

Thanks for verifying that I'm not crazy ;-)

whenever I do a ? I only get an authentication-key keyword never the
authentication keyword. I am using 11.2 12.0 and 12.1

Cheers,

Steve

Steve,

Interestingly enough, the documentation shows that you are
correct. However, the old command may still be on the routers:

Rack10_Router5(config-subif)#ip ospf ?

  authentication Enable
authentication

  authentication-key Authentication password
(key)

Cisco Internetwork Operating System Software

IOS (tm) 2500 Software (C2500-JS-L), Version 12.0(14), RELEASE SOFTWARE
(fc1)

C

I configured authentication using only the authentication-key command and
it works fine.

when you

 are using md5 you have to enter a key as well but for simple
authentication you

 just have to enter a password.

 Someone please correct me if I'm wrong.

 Hope this helps,
