RE: ospf authentication

But that's where it was weird (unless I'm not understanding what you are
saying).

I did this

Router ospf 1
Area 0 auth messag

r6(config-subif)#do sh ip osp | in auth
        Area has message digest authentication

and it seems that even with that turned on I can neighbor up with routers
and I don't even have to provide a md5 password anywhere. Is that called
type 0, 1, or 2? I'm getting the impression that what I've done was a
half-baked type 2. In other words it ain't truly type 2 md5 auth until the
int config "ip osp mess 1 md5 cisco" is applied. True?

There are 3 types

NULL, Clear text and MD5. So technically it can work without a password
using NULL authentication type
