Hi,
the idletimeout is being reset at the first router when there is no route to 192.168.5.1. This works fine. But the other routers idletimeout isn't being reset unless there is traffic flowing through the isdn line. So it drops the line after it's idletimeout expires.
You can check this by changing the idletimeout on the first router to 20 seconds and the second to 30:
When the route disappears on the first router it dials the other one.
The second router picks up the phone and listens for traffic.
The first router waits until its idle timeout elapses and resets it because the route is still not reachable via the primary interface
The second router watches for traffic but when there isn't any it drops the line after 30 seconds.
So you can do two things:
make sure there is traffic
or
make sure the idletimeout on the second router is very high
Regards,
Geralt

Subject: ISDN Backup With Dialer Watch
Hi,
My ISDN interface with Dialer Watch on it
is going down every idle-timeout and then dialing again.
interface Dialer1
ip address 1.1.1.2 255.255.255.0
encapsulation ppp
ip ospf demand-circuit
dialer pool 1
dialer idle-timeout 180
dialer string 0496406937
dialer load-threshold 127 either
dialer watch-group 1
dialer-group 1
pulse-time 0
no cdp enable
ppp authentication chap
ppp multilink
end
access-list 170 deny ospf any any
access-list 170 permit ip any any
dialer watch-list 1 ip 192.168.5.1 255.255.255.255
dialer-list 1 protocol ip list 170
----------------------------------------------------
interface Dialer1
ip address 1.1.1.1 255.255.255.0
encapsulation ppp
dialer pool 1
dialer idle-timeout 180
dialer load-threshold 50 either
dialer-group 1
no cdp enable
ppp authentication chap
dialer-list 1 protocol ip permit
According to CCO it should stay connected until the router gets the
route via primery interface.
Any idea's ?
With kind regards/ met vriendelijke groeten,
