OSPF authentication can be "enabled" using the "area <area-id>
authentication [message-digest]" routing process command or by using the
interface level "ip ospf authentication [message-digest | null]" command.
The interface level command supersedes the routing process level command.
Setting the authentication type to "null" on an interface specifies that the
interface will not perform authentication (type 0).
If the OSPF authentication type is set to type 1 (plain text) then the type
2 (message-digest) key command applied to the interface will be ignored. On
the flip side if the authentication type is set to type 2 a type 1 key
command applied to an interface will be ignored.
