Using one BRI inteface as a backup to two different locations

admin_2

Level 3

I have a 3640 router with a ISDN BRI interface. And I also have two 1750 routers each with a BRI interface placed at two different locations.

|------------- Router 1750

The 3640 has two serial links to these two 1750 routers.

Now when both the serial links are down I want to use one B channel of 3640 to dial to one 1750 and the other to dial to other 1750.

Can you please give me a sample configuration about how to do this.

If you can give me a URL of cisco site where I can find this kind of configuration it will be very helpful

You have to use dialer profiles.
