Load Balancing .. using 3 ATM cards... Is it possible?

[skk391]

Hi all,

I am looking to setup some load balancing using a Cisco router and mulitple ADSL lines.

I am trying to see if there is a workaround for us not to buy a leased line internet connection in a attempt to save money. I was woundering if it is possible to install 3 * ATM cards on a cisco router and then load balance all the connections?

We currently have 3 spare ADSL internet connection from some previous business projects and what to see if I can use them for this?

I have google the following config, wanted to see if this makes sense to anyone or if anyone has had any experience with this config ?.....
Sample Load Balanced ADSL Config
This sample config assumes 4 WIC1ADSL cards installed to load balance 4 ADSL circuits:
