Re: Backup ISDN auto disconnected

I am not able to test this, but it might be an idea:

On serial interfaces you can use " dialer enable-timeout" with a max value of 2147483 which is a lot of days.

You can not use this command with the purpose you have direcly on an ISDN interface, but I would expect you could use is on a Dialer interface.

(ISDN interfaces are not held down after a call has failed or completed because these interfaces support several possible calls at a time)

interface Dialer1

description ISDN

bandwidth 64

ip address

encapsulation ppp

dialer pool 1

dialer idle-timeout 180

dialer enable-timeout 2147483

dialer string 1234567890

dialer-group 1

interface BRI1/0

no ip address

encapsulation ppp

dialer pool-member 1

Re: Backup ISDN auto disconnected


At Serial interface try "backup interface dialer0" and set delay to get dialer to be fired by "backup delay 5 5" both commands to be configured at serial interface also put floating static routes i.e Serial 0 dialer 0 50

This will enable the backup configuration

and put the "dialer ideal-timeout 100" at dialer interface.

Hope this can help u out.
