Hi,
I have more than one link from different ISPs (IP Address assigned dynamically), on a 2811 router.
Each interface has different cost so if one interface is going down the cheapest interface must take it over. If the cheapest interface is back online the router must drop the current connection and route to the cheapest ISP connection.
I have tried Policy routing (with ping) only the main problem is how to do this with a wan interface that has a dynamic ip address.
And are there any other protocols that can do the job?
Many thanks in advance,
Gerard
