We are attempting to setup failover on a Cisco1921. In a nutshell, the end user has a T1 as their main connection, and has a cable modem as a backup solution. The LEC has not been much help with the flaky T1 connection, and it is prone to dropping multiple times throughout the week.
What we are trying to accomplish is setting up failover so that at anytime when the T1 on Serial0/0/0 goes down, the cable modem on gigabitethernet0/0 will takeover.
I have read some forum information on setting the static routes to higher metrics for the gige0/0 interface, but honestly am not sure what that would accompish.
Any help would be appreciated. I can upload a copy of the current running config if requested.
