Hi any one please help the following;
I have a Cisco 1721 with an ethernet port and ISDN port for backup.
The ethernet port is connected to the cable modem of the ISP broadband link.
Can I use the ISDN to backup that Ethernet Port ?
If yes, how I configure the static routing for the primary link and ISDN routing (DDR needed) ?
Anyone please help out.
Thank you.

I have succesfully used the dialerwatch mechanism for this. However, it took several IOS upgrades before it would work correctly.
