ISDN backup on a Cisco 1801 device

Unanswered Question
Nov 26th, 2008

Hi. Quick question. We have a Cisco 1801 device that uses ADSL as it's primary connection to the internet with an ISDN backup. Will the ISDN backup still work if we assign it a static IP (as opposed to auto-negotiate)? Thanks.

I have this problem too.

You should be fine, but without seeing your config, or knowing how your ISDN is backing you up (interface tracking or floating routes), it's all based on assumptions. :-)
