my question is the following, I have a cisco 2600 router connected to a T1 line and a 30 Mbps cablemodem line, I want the cablemodem as my primary connection and the T1 as my backup connection, when the cablemodem goes down, I want the T1 up and running.
I did this with priorities y the ip route command, BUT when I restart the router, the priorities changes, and when the cablemodem goes down and the T1 goes up I have to configure NAT manually. Im a begginner, so I need your help!!
here is my running config
