There are 2 ways to do OSPF authentication.

1. router ospf x
      area x authentication message-digest

    interface serial0
      ip ospf message-digest-key 10 md5 cisco

2. interface serial0
      ip ospf authentication message-digest
      ip ospf message-digest-key 10 md5 cisco

If you configure authentication according to the first
step then you must provide authentication for the
virtual link or if you don't want authentication on
the virtual link, put the command "area x virtual-link
x.x.x.x authentication null". If you do
authentication according to the second step, then the
virtual-link will work with no authentication or
further commands.
