Hello AmirReza,

you can use on each remote site router DDR: dial on demand routing.

the idea here is to make a call when traffic had to be sent out (interesting traffic ) and the primary link is failed.

A floating static route can be defined (with a greater AD) and access-lists can be defined for interesting traffic.

use the following doc


Hope to help
