Riccardo, You describe that you want all traffic originating from Net1 to traverse Router1, and traffic originating from Net2 to traverse Router2, in order to reach the Internet. That is called policy-based routing, and you can implement it with iproute2 on Linux.
You cannot both multihome using BGP, and policy-route in that manner. No currently deployed bgp-speakers can configure your routing table to implement that policy. In addition, although it seems like you have a firm understanding of what you want to do on this level, your organization probably lacks the necessary know-how to successfully deploy BGP, and your two ISPs may not even be staffed or equipped to deliver BGP sessions to you. If you want to undertake it anyway, I strongly urge you to contract a consultant who can help you and possibly your ISPs through the process. I hope this helps. -- Jeff S Wheeler [EMAIL PROTECTED] Software Development Five Elements, Inc http://www.five-elements.com/~jsw/
