We didn't get your attachment you will need to do it in ASCII. Or you can
send it directly. I looked at your configs. I have a hint for you virtual
links are "interfaces".

Subject: Ospf area authentication
I am running into a problem with authentication in ospf. RTR 3 and 5
(AREA 5) are authenticating via ospf and see one another's routes.
However, when I look at RTR1,2,4 the routes from 5 are not propagating
to them (1,2,4). Attached is a pic of the topology and the configs for
1,2,3,4,5. is there some type of redistribution that needs to occur
from an authenticated area?
