I think there is a LAN behind those three cisco 1700 routers. And maybe those routers set up a HSRP, so that the first one down will use the second and the third. In each router , just use static route to connect to you, Is that right?
If so, in your router, config three static route to those three cisco17, but they have diffence distant, to the first one is small , the second is higher, the third is highest. So , traffic will use the first Link and when it down use the second, and third.
When the first Link up , will reuse the first.
that is the way you do not change the remote config.(but the config you're using right now must same as I said)
Or , you can enable ospf in all the routers, but you must reconfig the remote routers.
If the remote lan is not a simple LAN, maybe there is a 3Layer switch behind the cisco17, you need check the config in the 3-layer switch.
