Greetings,

I have the following scenario where ISDN is backing up
the FR link between R1 and R2 .

     --- FR ---
R1 R2
    ---ISDN--

I am using dialer interface for ISDN config.

On int s0 , if I use "backup interface dialer 1" ,
then the dialer interface will go on standby mode .
Assume that I am using the backup interface command on
both routers , and that the serial interface on R1
went down , I notice that dialer interface on R1
become active but can not initiate a call to R2
because R2 dialer interface is in standby mode and is
rejecting calls .

Can this work at all? Or is it not a supported config

Thanks,
