Hi Jenny,
I did this lab a few days ago and its suppose to show invalid
authentication unless you put in the "accept-lifetime 0:00:00 1 jan 1993
infinite" & "send-lifetime 0:00:00 1 jan 1993 infinite" for each key chain
key. Another way to check is to see if you see the routes for the neighbor
routers.
