I have a cisco 1600 router, doing NAT for my LAN. I will have secondary ISP, of course with another IP's pool. How to configure router to route everything through new ISP gateway, and if something goes wrong, route in via old gateway?.
Will it work:
ip route 0.0.0.0 0.0.0.0 gate_ip1_isp1 ip route 0.0.0.0 0.0.0.0 gate_ip2_isp2 200?
If one link would go down, I would like to change my NAT outside address to another (of secodary ISP). Please help:-)
