How do I create failover in my Router?

By osehmicken ·
I currently have Cisco 2600XM Routers with two ethernet interfaces - one connected to my DSL modem and the other to the LAN on the two sites of my point-to-point link. I desire to add a microwave link as an online backup by adding an additional ethernet port ot each router on which I hope to connect the Radio equipment.

My question is how do I configure the router to automatically reroute packets through the microwave link when the primary link (DSL) goes down or fails?

Any lead will be much appreciated.

When the DSL fails the ethernet interface on the router connected to your DSL modem will probably stay up. Other than using some routing protocol over the DSL link, the only thing I can think of that might work for rerouting pkts over the microwave link when the DSL fails is object tracking. Take a look at

thanks, icmp. the link would have helped if i had ios 12.3(2)XE or ios 12.3(8)T BUT my ios is 12.3(5b)which means that some of the ios commands used are not supported.

Can I upgrade my ios? If so what are the requirement and how do I get the required one for my Cisco 2611XM Router with:
1. M860 Processor with 94208K/4096K memory
2. 32K non-volatile memory
3. 32768K sys board flash

Any hint or other solution paths will help.
