I have a question on the virtual-link authentication command. I have configured
 a virtual link with authentication to area 0 by stating area 0 authentication
under the ospf process and ip ospf authentication-key cisco under the interface
. I am getting all routes from R8 on R7 but not in the backbone, however I am n
ot getting any authentication or adjency errors.

CCO, states that not only do you put it on the interface but you must also do
a
area 1 virtual-link 200.0.0.5 authentication-key cisco

When I put it in the config to test the command I get errors on R5, when I take
 it out I do not get errors. This is from IPexpert lab 20-1. Does anyone know w
hat the problem is???

P.S. If IPExpert ppl are reading, it would be nice if your solutions matched w
hat you asked for in the tasks. Why are the labs always good but the answer key
s always lack an attention to detail. You asked for simple authentication yet y
ou have md5 in the solution. C'mon.
