Hi
I try to configure a cisco router to set up a failover between ADSL and ISDN lines.
The ISDN line only works if I call at the right dialer.
ADSL line also works if I call the associated dialer
The problem is that automatically switches between ISDN and ADSL is not working.
Can someone help me to understand the problem in my config file ?
Thank you,

Hi,
configure the following on your dialer associated with DSL
backup interface dialer (number of your dialer for ISDN)

Hi,
Why don't you try to use IP SLA:
conf t
ip sla 1
icmp-echo 4.2.2.2
exit
ip sla schedule 1 life forever start-time now
track 123 rtr 1 reachability
ip route 4.2.2.2 255.255.255.255 Dialer0 (you have 1.1.1.1)
ip route 0.0.0.0 0.0.0.0 Dialer0 track 123
ip route 0.0.0.0 0.0.0.0 Dialer1 50
You would need to adjust/tweak NAT if these are going out to Internet.
Regards.
