jackie_gx · ‎11-23-2009

I using isdn bri as our backup line. Below is the config on the dialer interface.

If the 1st dialer string is fail to connect, how long is the time/dial-attempt taken before it using the 2nd dialer string to dial?

interface Dialer1

ip address negotiated

encapsulation ppp

dialer pool 1

dialer idle-timeout 30

dialer string 123456789

dialer string 987654321

dialer load-threshold 1 outbound

dialer watch-group 1

dialer-group 2

no cdp enable

ppp chap hostname xxx

ppp chap password xxx

ppp multilink

end

Hello Jackie,

I have some doubts that multiple dialer strings are supported in the same interface.

see

you may need to use multiple dialer interfaces that attempt to dial the different numbers.

at IP routing level you can provide preference to a dialer using different admin distances

ip route 10.10.10.0 255.255.255.0 dialer1 10

ip route 10.10.10.0 255.255.255.0 dialer2 20

the time to move from one attempt to the other should be of some seconds

Hope to help

Giuseppe
