I have two routers, one wireless connected to ISP1 with optical cable, and the second one connected to ISP2. The second router is cisco 860 series, i will configure ACL lists and zone based firewall on it, so it need to be the router connected to the switch. How do i connect the two routers to share same network? Is internet from two providers going to be in a single network (speed up)? Do i need a third device to do this?
Actually want to apply this architecture, i don't know if it is possible, Even with a load balancer i can't keep internet from two providers?
