How to configure 2811 with 2 ADSL router 1

[greatanu]

Dear All,

I am working as a Sys Admin. Please give some solution for the below details

I already setup 217.x.x.x for one of our clients. All the Application activities going through that public ip address using NAPT (Network Address port translation) . We need to configure a backup/fail over line for the same client. So we took another internet line (ADSL) from a different ISP. These ISP having different public address. I am using CISCO 2811 ISR. My clients all application's communicating to our servers through the above IP address. So I can't change the ip address.How we can resolve this issue without changing the IP address?

Thanks in advance

You can't. You should have used a DNS name and not an IP and then you could change it at will.
