Backup interface problem

Unanswered Question
Feb 8th, 2007


I have a Cisco 2811 router,which has 2 fastethernet ports ,WIC-1T card.

1. WIC-1T is connected to teh ISP by means of 128KB leased line.

2. Fastethernet 0 is configured with Public STatic IP and connected to a switch,where 5 usres are connected with public IP.

3. Then the second fastethernet 1 interface is connected to a ADSL modem provided by the same ISP.

Now I want to configure this fastethernet 1 as the backup interface for teh Serial interface.

Please guide me how to achieve this.

Thanks and Regards,


I have this problem too.

Do not think this will work. You will have to change the administrative distance on one of these default routes.
