I don't say my config is the only way, or even the usual way to do it -
far from it. Indeed, often there are many ways to configure a router to
achieve the same result. I was only clarifying an incorrect statement
about OSPF authentication types.
Also, skimming through the URL you sent, I don't see any statement that
says a virtual link *must* configured the way they show, or a statement
that the virtual link must have the same authentication type as area 0.
They just show you one way (the usual way) to do it.
Page 17 of "Cisco OSPF Command and Configuration Handbook" by William
Parkhurst:
"In Cisco IOS Software Release 12.X, the authentication used on an
interface can be different from the authentication enabled for an area.
When using Cisco IOS Software Release 12.X, the authentication method
used on different interfaces does not need to be the same.
Authentication can be turned off on selected interfaces using the
command 'ip ospf authentication null' (see Section 19-1)."
