I'd like to have my Cisco router failover from a primary WAN to a secondary WAN interface when the primary stops routing traffic. Neither WAN is running any routing protocol, these are residential-type WAN connections (ie, DHCP).
I don't have any need for maintaining source addresses. In either case the traffic would be NAT'd out whatever the appropriate WAN is.
How do I configure this setup in iOS?
If it matters, I have a Cisco 890-series branch router. Thanks in advance.
