I have an issue that I am trying to get resolved with regards to fail over. Here is an overview of my network design and I will list what I am trying to accomplish.
I have 2 Internet connections one of which is a T1 attached to a Cisco 1601 router with a firewall protecting the internal network. The second connection is a Microwave connection attached to a PC performing routing. I have drawn a rudimentary design below of our current configuration.
What we want to accomplish is to have some type of failover in place for our Internet connections. We have purchased a Cisco 2611 with an extra eth port to accomplish this task.
I would like to place the 2611 connecting both of our Internet lines into the 2611. I would like to know how I can configure this scenario to provide fail over support for the 2 Internet lines. Can the 2611 provide this capability? How would I configure the 2611 to use the T1 by default and then the microwave if T1 fails.

decision. To do this we require the switch to do...
