Hi,

I want to configure cisco router 1921 and 1941 by existing router configuration for disaster recovery

If our running router is damage, we will sassily running our network by plug and play with backup router.

Thanks,

You can either configure a backup router as a hot spare or use a First Hot Redundancy Protocol such as HSRP for automatic failover.

Using a hot spare is fine if you are ok with manually swapping out the devices. The downsides being that you will have downtime and you need to ensure any changes to the live router are updated on the hot spare. How long will it take (worst case scenario) for someone to swap them out? Can you afford that amount of downtime.

I would be looking at HSRP or similar to be honest, a hot spare is thing of the past really.
