Re: Backup routing over isdn

Can you please provide some more info.

What are these interfaces - Serial/Ethernet?

Static v/s Dynamic routing?

What kind of ISDN backup is this - Backup Interfaces, Floating Static Routes or Dialer Watch for DDR Backup?

If you can provide an example with some IP addressing would be great!
