Hi Nate,
Thats right, if you have authentiation enabled for the whole area all the
interfaces automatically inherit this.''
If U want to disbale the authetication for a particular interface or the
Virtual Link you have to use the commad-
area <transit-area id> virtual-link <router-id> authentication null on both
sides.

Subject: ospf area authentication
Hi All.
When configuring area authentication in OSPF, it looks to me like interfaces
that are put in that area are inheriting the authentication by default.
For instance, if I have simple authentication in area 245 enabled, and I
have a bri interface in that area, it will inherit the simple authentication
parameters even though I don't explicitly state "ip ospf authentication" or
"ip ospf authentication-key xxxxx"
Is this correct thinking and correct behavior. Oh, and I do have a virtual
link transiting area 245 with simple authentication as well.
Any help?
Thanks,
Nate
