I have only one ISDN interface and ISDN line and I wanna connect to different locations(Dial different ISDN no.) with same ip address. For example, When I fail to dial first ISDN number, it will automatically dial to second ISDN number. How can I config it? May I config as below?? Many thanks.
interface Dialer1
ip address 192.168.1.2 255.255.255.0
ip virtual-reassembly
encapsulation ppp
dialer pool 1
dialer idle-timeout 90
dialer string 11111111
dialer string 11111112
dialer load-threshold 1 outbound
dialer-group 1
ppp multilink

Yes when you put more than 1 dialer string the router will attempt the first dialer string. If it is not successful the router will attempt the second dialer string. And if the second one fails and there is a third one the router will then try the third dialer string.

Thanks a lot. one more question. Will it happen one channel dial first number, the other channel dial second number?
How about if i use two dial interfaces, does it look better?
For example,
interface Dialer1
ip address 192.168.1.2 255.255.255.0
ip virtual-reassembly
encapsulation ppp
dialer pool 1
dialer idle-timeout 90
dialer string 11111111
dialer load-threshold 1 outbound
dialer-group 1
ppp multilink
interface Dialer2
ip address 192.168.1.2 255.255.255.0
ip virtual-reassembly
encapsulation ppp
dialer pool 1
dialer idle-timeout 90
dialer string 22222222
dialer load-threshold 1 outbound
dialer-group 1
ppp multilink
ip route 172.12.254.0 255.255.255.0 Dialer1 10
ip route 172.12.254.0 255.255.255.0 Dialer2 20

I believe that I have gotten ISDN to dial 1 location with one channel and a different location with the second channel. I am not clear about the logic of having 2 dialer interfaces with exactly the same IP address and exactly the same destination network. I am guessing that it would work but would be a bit more comfortable with the approach of having 2 dialer strings in the same interface.
