I don't think I understood your question properly, but...
In OSPF, when you are joining an area through whatever means, in this case
MD5, you must conform to that area's authentication method. For example, if
I was creating a virtual-link to another area that was using MD5. I would
have to specify the authentication method in the virtual-link setup.
If you do not specify the authentication method, the virtual-link would
never come up.
Can someone correct me if I am wrong.
