I have configured the fatkid lab for ospf. What I find is that the Bri0 on
either router R3 or R2 does not come up when th frame connection on s0
fails. I also find that I cannot ping any of the route that shows up as
directly connected. take a look at the config and debug below. Please
help.Take a look at the sho ip ro on R2 below. Also take a look at the sh
dialer on R2 and R3. It shows connected. But a ping does not work.
What I am missing.
