Configuring failover

HI,

I have to configure a fail over link to my router. It should be such that whenever the main link went down for 5 sec, it automatically shift to backup link.
Can any one let me know the steps????

Thanks

You can try researching about "cisco HSRP" or "VRRP" for generic router.

Hope to help.[/b]

what are the requirements? single router, dual router, single router with dual WAN and single/dual LAN?

Single router with dual WAN LINK. I want to configure it, that whenever the main link went down it goes on backup link after 10 or 20 sec. And again come back to primmary one if it is stable for 2 or 3 mins.

I have tried this through SDM, but failed.

Thanks

Could use backup to do this.

interface Ethernet0/3
backup delay 0 10
backup interface Ethernet0/2

when eth0/3 goes down, wait 10 seconds and eth0/2 takes over.

Thanks,

I will try this tomorrow.
