the network scenario is as follow
Internet Edge router--E0--Router 28XX --E0--ATM Router 38XX --fiber pvc--ISP.
i wanted to divert my default route (internet traffic) to the ISP.
The default routes has been added in internet edge router pointing towards the 28XX and in 28XX towards 38XX ATM router.
The connection between 28XX and 38XX is Ethernet connection which will never goes down so my 28XX router will always through the packets towards 38XX.
What i wanted is that whenever the ATM PVC goes down, my 28XX should divert the traffic to the next lower metric route which is my redundant path to the ISP.
end result should be - 28XX should use secondary path to ISP when primary is down eventhough it has been not connected to the ISP. (should track the ISP ATM PVC to take decision for secondary route).
Any suggesion with config examples will be highly appreciated.
