Well, that nailed up the ISDN connection for good, but OSPF adjacencies
still did not form....
I had to change my dialer map statements to dialer string statements...
dialer string 3333 on R1
dialer string 1111 on R3
...and it magically worked.....now, why? Why did it have a problem with
the dialer map ip statements? I will try to figure that out, but at least
I know now what I need to do in this scenario.
