There are 2 7200 routers that connect to different providers. Traffic ends up where it is supposed to. The problem is that we have intermittent slow response times and some applications that don't work properly over the internet. My suspicions are that some of the traffic is returning over the smaller 512K line and that is causing congestion.

One interface of what? The 7200? Does the 7200 connect to multiple border routers?

It's very difficult to control how traffic comes back into your network over the Internet. Entire books by Berkowitz, etc. have been written on this topic. But it's not necessarily a problem. If the traffic all ends up at the 7200 and the 7200 is configured correctly with the static routes that you mentioned, the traffic should end up at the right place. What problem are you trying to solve? By the way, John makes a really good point about pinhole congestion. See his post too. Thanks.
