Implementing a Failover
We currently have an SDSL which we would like to use as a failover once we get our T-1 line. The modem which is currently being used for this sdsl is a NETOPIA.
There is another modem which is a dedicated PRI T1 for voice but is currently not providing data. It it connected to a modem with ports which read WAN-T1, DSX-1, DBU. The WAN-T1 and DSX-1 are connected but the DBU is not.
How do I implement a failover? I've never done it.

Answer Wiki:
You should implement routing on your layer 3 switch which is connected to both routers. All you need are to routes. Here is a cisco example:
ip route 0.0.0.0 0.0.0.0 Router1IP
ip route 0.0.0.0 0.0.0.0 Router2IP 100
This will set priority to Router1 and if that fails, you have the second route.

I would like to add the current setup.
Cloud>>>Netopia Modem >>>1841 Router >>> 3560G Switch >>>2960G x2
This is how the connections are setup. if you can visualize it. The configuration will be done at 3560G Switch?
You are correct. Make the changes on the 3560G. When have your T1 setup connect that router to the 3560 as well and use the routes specified above where Router1 is your T1 router and router2 is your 1841 router.
