isdn bri dial backup for pppoe dialer

[rinma]

Hi!
Please help me!
I have 1721 router with WIC ISDN bri card and 10 Mbit/s card.I have configured router for adsl connection with pppoe dialer and that works fine.
Now, I have a problem how to configure ISDN backup link!!!
Does anybody have any sample configurations??

There are a few solutions here but I'd recommend a floating static route with a dialer interface :
1 Configure the dialer interface - e.g. dialer1
2 If your routing table is like this
route 0.0.0.0 0.0.0.0 ATM0

Then add the following :
route 0.0.0.0 0.0.0.0 dialer1 50

This will bring up the dialer interface and route all traffic through it in the event of the ATM (dsl) going down.

Don't forget to set the correct encapsulation on your dialer int.
