dual ISP carriers, seamless failover

My objective for a client is this:
1. Connect two broadband on-ramp routers, each connected to a different ISP.
2. Configure each router to see the other so that when one ISP fails
the other router will pick up and route messages for router which lost its internet connection.
(For example, router A will have an "output" port connected to a port on router B,
and router B will have an "output" port connected to a port on router A.)

Question. Can someone point to some literature and products that support this concept?
How would I create this configuration so that it will work (i.e. no circular routing, Do I need a layer 4 or is layer 3 enough?, etc.).
Please feel free to given me some of your thoughts and experiences.
