Cisco 2811 - Load balancing 2 ADSL links on SAME network

You read it right.  One of our remote locations has one provider delivering two ADSL lines that are on the same network and the site wants to use those two lines to load balance on a 2811.

The one "network" is x.x.x.71 255.255.255.0 with a default gateway of x.x.x.1.
The second "network" is x.x.x.80 255.255.255.0 with a default gateway of x.x.x.1.

There are no other provider options and they existing provider doesn't seem to be willing to provide an actual seperate network.

Is it possible to load balance 2 lines on the same network?  And if so what would that config look like?

Thanks

well the ISP gave you basically 2 public ip addresses to use. you can't assign them on the same router and load balance but if you've got a second router you might look for something like HSRP to accomplish your task

When I first read this question, that was the thought I had . . . two HSRP or VRRP routers (eg, A and B), each with a connection to the provider and each router configured to be the back up for the other. Then set half of the users to use A as their default gateway and set the other half to use B as the default gateway.

Good luck,
Steve
