Title: OSPF Authentication and Virtual Links
When configuring OSPF with multiple areas, I tried implementing md5
authentication in Area0.
I had the whole mess working without the authentication, and the the
virtual link was working fine.
When I enable authentication in Area0, the virtual link no longer
worked.
I pounded on it for a while and just couldn't make it work. I tried a
few things with no success:
-applying authentication parameters on the virtual-link statements
(seemed reasonable)
-applying md5 authentication to all areas and interfaces *everywhere*
on *every* router (shotgun approach)
(I was hoping that those desparate measures would yield a working
config where I could remove things one-by-one to determine what was
really necessary)
The debugs would show (I'm recalling this while at work)... "expected
type 2, got type 0 for ospf authentication" or something like that
(sorry for not being exact).
In the end, I removed all authentication statements and the world
worked again.
There's a "stunt" here... does anybody know what it is?
Thanks for your help everybody!
Richard
