Mindiani,
In this configuration, there is no switch sending LMI to the routers.
The router declares the line protocol down after three missed keepalive
intervals (10 seconds each, by default).
One way to fix this problem in back-to-back frame relay configs is to
add "no keepalive" under the serial interface config.
This assumes you have Router1 as the DCE end of the cable.
Cheers,
Curtis
